If every driver on the road today was never drunk/distracted/enraged I would agree, but the reality is that humans driving cars kill other people every single day. We should fix this with a better system. Tesla and Waymo seem to be making progress. I don't expect them to be perfect but in the long run this will save lives.

You seem to be implying that in the short run it's ok for them to kill some extra people. One, I don't think that's necessary; Waymo is a good example of how a safer approach is also apparently no less effective. Two, you're presuming that we will get to self-driving cars that are economically viable and safer than current human-driven ones, something that is not a given. And three, it's not clear to me who gets to decide exactly how many unwilling people should be sacrificed on the altar of technological progress, but I hope it's not us and it sure shouldn't be Musk.

Here's a video of Waymo car in Phoenix. Around min. 17 it gets confused by a cone and stops in the middle of two lane road, hugging both lanes.

Then google sends support but just when they arrive, the car drives away from them.

They were lucky it didn't lead to an accident and as long as they keep the fleet to 600 cars then yeah, the accident rate will be much lower than Tesla's AutoPilot, shipped in more than a million cars.

My point is not to rag on Waymo just to inject some reality.

We don't have a choice between "safe and unsafe" way of developing self-driving software.

We have a choice between "test software we know can't handle all situation on real roads and make it better based on that testing" or "we'll never have self-driving software".

Except the other option will rather be: "U.S. doesn't allow testing of self-driving software on real roads and a Chinese company will develop it and will capture a trillion-dollar market in U.S."

The Waymo car in that video drove extremely safely give that it was confused. It was conservative and thought it might have seen and obstacle so it stopped. Did this inconvenience other drivers? Absolutely. But it was not a major safety risk. In fact, slowly coming to a stop is the legal and correct thing for a confused or impaired human driver to do. In comparison, Teslas seem to rapidly and suddenly brake for no explainable reason while traveling at fast speeds and do so routinely. Further, Teslas have other safety issues which are indicative of sloppy design (such as the fly-by-wire passenger doors that will trap back sheet occupants in the car if the electronic system is disabled). This is a failure of Tesla specifically, and regulating to stop it wouldn’t really slow down others like Waymo.
> ”Teslas seem to rapidly and suddenly brake for no explainable reason”

The reason is widely known. Phantom braking is caused by rogue radar reflections that confuse the car into thinking there’s an obstruction in its path, activating the AEB automatic braking.

The real question is, why does it happen more often with Teslas than with other cars equipped with radar AEB? Maybe Tesla’s is just more sensitive.

heh, i guess their fix to that is to just get rid of radars altogether.
Exactly. There's a big difference between approaching this problem with a "first do no harm" perspective and a "move fast and kill a few people" perspective.

And this part from the previous poster strikes me as a big problem: "They were lucky it didn't lead to an accident and as long as they keep the fleet to 600 cars then yeah, the accident rate will be much lower than Tesla's AutoPilot, shipped in more than a million cars."

That seems like an excellent reason to keep the number of active cars very, very small. Rather than, as stated, an excuse for shrugging at a death rate at least 1667 times higher.

100% agree! And I don’t think the approach needs to be “first, do no harm”. I would be very happy with “move at a normal pace and do your best not to kill anyone.”

But “move fast and kill people” is ludicrous and it’s exactly what Tesla is doing.

> We have a choice between "test software we know can't handle all situation on real roads and make it better based on that testing" or "we'll never have self-driving software".

This is like saying that we'll never have a cure for cancer if we can't experiment on the public without their consent.

The bar for medication, at least, is proving safety first before testing on large amounts of people and allowing the public to buy it.

Except for vaccines, apparently...

It's also entirely possible Waymo hasn't achieved peak perfection in its software development practices despite doing better than Tesla, and that another entity could do it more safely.

How many unwilling people are sacrificed because we won't ban alcohol and all impairing drugs without exception and then enforce those bans with immediate, Judge Dredd-style summary execution?

I bet you that'd reduce traffic fatalities dramatically too.

How far do you want to go to 'save lives'.

I guarantee you with 100% certainty I can design a society that will 'save lives' at every turn for every single activity, and I can guarantee you with 100% certainty you wouldn't want to live in it.

You seem to ignore that we've already tried banning alcohol and currently ban many drugs. We scrapped banning alcohol for a reason.
you are arguing a fake hypothetical. Tesla accident data shows that their autopilot feature reduces accidents.

fortunately our regulators don't take a one size fits all approach for how new technologies can be developed

It doesn't, as it compare general rates with self selected "good driving conditions" as defined by the software - only highways, only good enough weather, only good enough maintenance state of the car.
Your notion is that everything is fine because according to Tesla, a company with a leader known for telling whoppers, they are killing less people on net?

Even if we trust them on that stat, which I certainly don't, that still doesn't mean they aren't killing people unnecessarily.

If FSD is accurately described as “not always worse than a drunk driver” then please remove it from the roads.
I can't withdraw my consent to share the road with intoxicated or distracted drivers. That's just a fact of life. That doesn't mean I shouldn't be able to withdraw my consent to share the road with Beta software.

Plenty of businesses are able to build very effective safety mechanisms for motor vehicles without subjecting the general public to Beta software. To me this is a case where the ends do not justify the means.

I understand your point, but I would frame it stronger: Indeed, we, as a community, have withdrawn our consent to share the road with intoxicated drivers. You break laws if you drive intoxicated. That beta software doesn't break any laws, but maybe it should.
> We should fix this with a better system.

What if we made driving tests far more difficult (otherwise, you can drive a 50(?)CC moped that tops out at 35mph)? What if we had government subsidize rides home after going out drinking? There are a lot of solutions that don't involve "let companies test 5000lbs autonomous vehicles on public roads." Heck, those companies have enough money let them buy a city and test it on the now private streets.

> Tesla and Waymo seem to be making progress. I don't expect them to be perfect but in the long run this will save lives.

Let's assume for a second your unstated assumptions I was alluding to above are correct. This is the only way to make a better system and that system has to be tested on public roads. Why do we allow two private companies to reap the inevitable huge monetary rewards when we all pay for that system with a higher increased risk of dying in the meantime?

nah. just because some drivers do stupid things does not mean that we should allow this "FSD" travesty. The thing is: if you're a human driver and you screw up you pay the consequences. It's codified in the law and you are fully aware that there are consequences if you don't follow the rules.

Now, if you drive one of these "FDS" cars and it ends up in an accident where people die, who is responsible? Are you responsible? Is the car manufacturer responsible? Do we just write it off as a freak accident with 1 in a million chance of happening again?

FSD != auto pilot
yes of course. fsd is only 3 letters but IMHO they’re both lies.
