Good grief, two skateboarders lives saved by a Waymo in two consecutive comments.

A couple of weeks ago I came across a biker partially lying in the road, trapped by his bike. I parked my van at an angle, so if it was hit from behind it should roll past him. I jumped out and performed an assessment (I'm a qualified, OK: certificated first aider). I diagnosed "pissed" and ascertained he was unharmed. We got his bike in the back of the van with the help of some concerned pedestrians who initially thought I'd hit him. I drove him home.

I'm not sure a machine would have noticed an odd lump next to a lamppost, with a civic rubbish bin next to it, in the rain. What sort of sensors do these Waymo things have? They will have to be really, really clever and seriously expensive.

I don't deny that eventually a vehicle with enough decent sensors and some fancy processing will outperform me but I've managed 30+ years on the road with just a few scratches, a broken wing mirror and a rear ending from an articulated lorry.

I've managed to return a hire car around Napoli (Italy) after a couple of weeks without any issues! That may not sound too impressive but have a look at the state of vehicles around St Antonio Abate etc - it looks like the locals play bumper cars. May I also note that I'm a Brit and we drive on the left. Italians don't. So I can adapt to local conditions. I have also driven across large parts of the rest of Europe and the north Americas. I can adapt to local driving styles from the "use your entire car as the indicator" as seen in the Amalfi coastal area (int al) to "no after you" as you tend to see in large parts of the UK and Eire. I can deal with all the different regulations. A classic European one you don't see elsewhere is the white diamond sign with a yellow centre that indicates that you have right of way until it is cancelled with black stripes. Then there is the French "priority to the right" thing (which has also pervaded the UK somewhat wrt roundabouts).

I can negotiate this with ease: https://www.google.co.uk/maps/@51.5628345,-1.7713341,110m/da... and this on a wing and a prayer: https://www.google.co.uk/maps/@48.8654026,2.3222455,464m/dat...

I'd love to see a Weymo navigate those.

Though Waymo et al aren't really competing with unusually good drivers, more with average drivers and they are probably safer there, on the roads they have been trained for.

(one study - 100% reduction in the frequency of bodily injury claims and a 76% decrease in property damage -https://www.ktvu.com/news/waymo-says-its-driverless-cars-saf...)

The thing is most drivers should not be allowed to drive given their low training, driving standard, general lack of empathy and/or medications or substance abuse issues but society incorrectly assume driving is a right while it should be considered a privilege you earn and that can be revoked anytime based on regular tests + eventual tickets.

I estimate at around 20% the amount of drivers that really should be allowed to drive given their current driving standards. Possibly more could be allowed after additionnal training and showing better driving standards knowing their license is at risk.

Ironically, it is very unempathetic to claim 80% of drivers lack empathy.

Your super-claim that you are indeed empathic because you're concerned about everybody else does not justify the lower-level empathy violation.

You have been P.C.'d

> Ironically, it is very unempathetic to claim 80% of drivers lack empathy.

Well I may not have phrased it correctly but I am not claiming that. Lack of empathy is one of the various causes of a majority of drivers being unfit for driving.

Ahem... "lack of empathy", how do you plan to quantify/measure that.

Also, I was under the impression that in most countries on this planet, the priviledge of being allowed to drive a car is handed out with the drivers licence, which in most countries, you actually have to have training and a test for. I also thought it was normal practice that these licenses also get revoked, based on tickets...

The only gripe I have with the system is that elderly are not automatically subjected to a regular test of their mental faculties and remaining sight. I am getting sick of 90 year old grandmas killing 3 year olds "by accident".

> Ahem... "lack of empathy", how do you plan to quantify/measure that.

That is a tricky one.

> Also, I was under the impression that in most countries on this planet, the priviledge of being allowed to drive a car is handed out with the drivers licence, which in most countries, you actually have to have training and a test for.

Training which varies a lot depending on the country. I did a lot of hours + 3000kms under supervision of my father + dedicated classes with emergency from 90kph to 0 braking on varying surfaces, including having 2 wheels on gravel and 2 wheels on pavement to be able to handle situations where the car would naturally go sideways. My Mexican partner in comparison took a handful of classes using an automatic car and only passed the test using a simulator and there you go she had her license.

> I also thought it was normal practice that these licenses also get revoked, based on tickets...

It needs an absurd amount of them for it to happen and we should still require periodic tests and knowledge refresh of the rules of the road.

> I am getting sick of 90 year old grandmas killing 3 year olds "by accident".

I am pretty sure they represent a marginal fraction of the accidents/killing compared to distracted drivers.

> I am pretty sure they represent a marginal fraction of the accidents/killing compared to distracted drivers.

In Germany, if seniors end up in traffic incidents, they are in a vast majority of cases ruled responsible for causing them [1]. They may not be the group that causes the most accidents, partially because they drive less than someone in their 40s commuting for hours every day, but the difference of at-fault cases is nonetheless significant.

vThanks for postng this. It is a small step towards ensuring public safety, but it is a datapoint which might get older people to think, or more likely, revolt. Still, thanks for helping to fight the tyrany of the eldery.
Distracted or elderly, we seem to agree that regular re-evaluation of drivers would be necessary.

And yes, I know that the standards of different countries are vastly different when it comes to obtaining a drivers license. I could have bought a drivers license while in south america. I am writing this because I am blind. Entertained the thought just for fun and to be able to show how broken the system is.

Re old folk driving I think that may be a problem that could be solved by self driving tech. The trouble with just banning oldies when they are getting less good is that a lot of them rely on the car and cause less deaths than teens driving who are much less reliant on cars. I'm wondering if the tech will kick in in time for my mum who's 86. My other relatives have had to stop around 90 due to hitting stuff.
"I estimate at around 20% the amount of drivers that really should be allowed to drive"

I don't know where you are but in the UK the driving test is pretty tricky. I failed it twice before passing and that was before it had the theory test added on. That was 30 years ago.

We all have our own perceptions of other drivers but you do need to try to think in their shoes. Today, whilst driving home I noticed a police car lights to the left and decided to indicate and move from lane one to two to give them room. The land rover behind me decided to undertake me and blunder through in lane one. Now the LR made a perfectly legitimate move - stay on track. They then undertook me (naughty). They did their thing and came across as wankers.

I think this ignores the way society is governed. It's easy for an engineer-mindset to think the bar to be cleared is "better than the average driver". But these systems must operate in a society that is often employing something other than an engineering mindset.

I doubt the public and their political representatives (absent regulatory capture) would turn over control to a mere average robot. Do you think, for example, most people would be okay in a drone airliner that is equivalent to the average pilot? I suspect most people would balk at the idea. A large part of the public policy piece is about trust; humans have evolved to understand and predict the behavior of other humans which leads to mental models about who can be trusted and who can't. We don't have those same evolved intuitions about robuts and, when combined, with our natural risk aversion biases, it's going to take a lot more than "average performance" to get society as a whole to fully trust robotic safety critical operations.

>(absent regulatory capture)

Yes trial attorneys will keep the bar very high for safety. As they should. But the bar in not infinitely high. Tech companies are salivating to disrupt the transportation market. They want a piece of your car payment, your insurance payment, your taxi spend. Insurance converts the minute risk of large accident costs into fixed premium payment. Lobbying helps convert financial capital into political capital and then into regulatory change. Our political process tends to follow the desires of the top 0.1% more than the bottom 40% combined.

Our current regime of car infrastructure was once unthinkable. Entire neighborhood were bulldozed to make way for highways. Yet today the government paying for highways, roads, and mandating each building be surrounded with amble parking is the status quo.

I’m not sure the original intent of the national highway system can be chalked up to the interests of the 0.1%. It’s generally attributed to national security, which is a very public interest.
While Eisenhower was inspired by the German autobahn, military use of roads was a sales talking point. The real reason for highways was to allow favored Americans to live in detached houses while still accessing city jobs. We could have it both ways!

Rail is a much more efficient way to move troops and equipment. Modern warfare requires lightning fast movement which means cargo planes. Eisenhower himself used a “New Look” policy of relying heavily on nuclear weapons so that the army could be scaled back.

After looking into a bit, I think you're right about the impetus of the national highway system. But, while rail is more efficient way to move materiel, it's also less flexible and more vulnerable. I think in that aspect, a highway system is probably preferable.
I probably should have said better than the average taxi driver as those generally don't include teenagers, 90 year olds and so on. Re the politics say human drivers in an area cause 10 deaths a year vs robot causing 6. Do you think voters are going to say we should have more deaths because humans doing it is better? That said I think people generally expect automated systems to be safe and probably self driving cars will be when they de glitch them. And then self driving cars will compete against other self driving cars more than against humans.
They have multiple radars, lidars, and cameras. They're far more capable of detecting obstacles than people are.
They have different capabilities, but it doesn't follow that such technology is better than the built-in tech in homo sapiens.
One under appreciated benefit they have is the "eyes" on a Waymo car are mounted at the corners and high above the roof, giving it a much better vantage point that just sitting in the driver seat.
It is demonstrably better. They see more and react faster. They can see around obstacles that humans can't and they never get tired or distracted.
See more in the rain y dark? Sure.

But can they look at a driver's face and realise that they are distracted with their phone and haven't seen you?

This is an important point. Humans have evolved a way to intuit the thoughts and behaviors of other drivers. It’s why people who are mentally ill are unsettling; it’s very hard to pick up on their intentions and course of action. That’s why in think the hurdle isn’t “better than the average human driver.” Because humans won’t trust a machine in the same way as another human, the level of safety for AVs may have to be much, much greater before the public as a whole trusts them with safety critical decisions.
Yes they can. They are absolutely capable of looking at gestures. That matters a lot more when you're trying to determine the intent of a pedestrian than a driver. If it's another driver, the system can also do real time physics calculations to avoid a vehicle straying into the av's trajectory. And they might even do some kind of computer vision with other drivers to determine intent. Also if another driver just hits the car because they were distracted, why would the AV be at fault?

These are really sophisticated systems and they've really thought of a lot of issues. All of these companies have hundreds, if not thousands of engineers who have been working on this problem for over a decade, as well as an army of lawyers trying to get things into compliance. I don't think "well it can't do x as well as a human" is going to hold up in 10 or 20 years when these systems are clearly much safer. Human driven cars will eventually be uninsurable.

> All of these companies have hundreds, if not thousands of engineers who have been working on this problem for over a decade,

So do a lot of tech companies that make a lot of dangerous, fraudulant, or just bad products, or that try to develop technology that never comes to fruition.

The tech is impressive, but that doesn't lead to an assumption that it must be able to do whatever is needed. I've seen enough tech hype cycles to know them when I see them. In the end it will have great strengths and great weaknesses, and we should learn what they are.

>They are absolutely capable of looking at gestures.

But 'looking at gestures' isn't the same thing as having a real-time interpretation of the sensors. This, to the point of another comment above, may be conflating 'perception' with the larger problems of 'self-driving.'

Humans see a gesture and understand the meaning very fast because we process a lot of communication on the subconscious level. If you read the safety report of the Uber incident, it shows that the self-driving system could 'see' the pedestrian, but it struggled to effectively classify them. To be fair, that was years ago and another company, but we (as the public) don't have much insight into how good (or bad) the software is.

So 'seeing gestures,' 'correctly classifying gestures', and 'correctly classifying gestures in a time-sensitive manner' are varying levels of difficulty. The last one is the one that matters for safety-critical operations, and the requirements change with the velocity of the vehicle. IMO, there should be a regulatory framework that addresses a baseline of performance on these systems.

That comparison is a very common sales technique and fallacy: Take two products, list the things product B does better than A, and therefore B is better!
I'm not sure I get what you're saying. I'm saying the waymo is probably better than me at detecting and avoiding obstacles. That is the point of this thread.
I understand what you are saying. I'm saying that argument presented doesn't support that conclusion (though it may be true for other reasons).
I do want to clarify that my comment: the skateboarder would not have died. Waymo provided a larger margin of error for the board rider than a human could possibly have.
No need for this comment - you deployed an anecdote from personal experience. That's fine.

However you finish with an assertion with no evidence. Care to elaborate? What on earth does this actually mean:

"Waymo provided a larger margin of error for the board rider than a human could possibly have."

Humans cannot react very fast, this incident comes down to fast reactions and the good all around vision in the Waymo. On these measures a human isn't competitive.
And this is just something you've decided is true or...? One sensor with determinate output based on an input from a finite set, sure I won't argue with you, but in any domain with indeterminate outputs coming from inputs that are of an infinite set, there is no meaningful notion of reaction time, there are imperfect decisions made with incomplete information at a moment during the dangerous spiral of number of possible responses shrinking and information completeness growing, (should I react now or wait until I have more information about how effective each of the dwindling number of path s available to me are shrinking) too name just one complexity.

I believe that we will get there and sooner than skeptics believe, but we are so far away from machines having driving skill equal to that of the average human driver, who happens to be driving while distracted 99% of the time.

Here an objective difference is described: a Waymo vehicle reacted to new visual information in a direction that a human driver would not be likely to be looking.
> I parked my van at an angle, so if it was hit from behind it should roll past him.

Good tip!

The yellow diamond with a black stripe puts you into "French priority to the right" mode and it's not restricted to France, it's pretty common across the continent.

I like how it's indicated with road paint here in Switzerland, e.g. https://www.reddit.com/r/Switzerland/comments/wp6clo/who_has...

> I'm not sure a machine would have noticed an odd lump next to a lamppost, with a civic rubbish bin next to it, in the rain.

As opposed to what? You don’t have RADAR, or LIDAR, or echolocation, or any other way to “detect” a person in the road. You have human vision.

This is the idea behind Tesla FSD. If human vision is good enough, computer vision is good enough. We have cameras that can approximate human vision. All the other companies using sensors are doing so as a crutch, because they didn’t have the chops to solve the vision problem.

The correct question to ask isn't "is computer vision enough", it's "if humans had LIDAR sensors, would they use them to cause fewer road accidents".
I really don't need LIDAR. I have roughly 3 billion years of evolution and the end result - eyes, brain etc.

LIDAR is simply a sensor and a very inferior one, in general, when compared to my visual system. For starters it needs something to interpret it. My eyes have a 52 year old brain stuffed with experience behind them and it isn't always a hindrance!

I can reason about other people's driving style and react accordingly. I can also describe my actions and reasoning on internet forums.

I really do not want an inferior sensor such as LIDAR inflicted on me, nor would I want it to be the sole source of information for something that conveys me.

Quite - I don't have those sensors but I do have madly myopic (sort of corrected) stereoscopic vision and a brain, with 30 odd years experience in it. Oh and I have ears. I generally drive with the window down in town. I can look left and listen right.

My office has an entrance onto the A37 in Yeovil (1) Bear in mind we drive on the left in the UK. Picture yourself in a car next to that for sale sign and trying to turn right. That white car will be doing 20-40 mph or much more. In the distance is a roundabout (Fiveways) which is large enough to enable a fast exit and people love to accelerate out of a roundabout. As you can also see this is a hill so the other side is quite fast because cars have to brake to keep down to the speed limit of 30 mph. That's just one scenario.

Anyway, back to your idea that Tesla FSD (Full Self Driving) ie RADAR, LIDAR etc is equivalent to "me" is debatable. I do have my limitations but I can reason about them and I can reason about what FSD might mean as well.

You assert: "If human vision is good enough, computer vision is good enough." People and computers/cars/whatevs do not perceive things in the same way. I doubt very much that you have two cameras with a very narrow but high res central field of view with a rather shag peripheral view which is tuned for movement. Your analogue "vision" sensors should be mounted on something that can move around (within the confines of a seatbelt). Yes I do have to duck under the rear view mirror and peer around the A pillar etc.

I have no doubt that you have something like a camera with a slack handful of Google Corals, trying to make sense of what is happening but it is really, really complicated. I actually think that your best bet is not to try to replicate my or your sensors and actions but to think outside the box.

Have you ever considered a drone?

tesla vision doesn’t have an agi behind it though lol.

and why gimp ourselves. if we had an extra sense to navigate with we would 100% be using it.

A rock instead of a hammer is also probably "good enough". Still a bad idea.
