My argument if that a mix of human plus self driving cars as yet to be tried at massive scale (eg. 50% self driving / 50% human or whatever that percentage is). With this mixture I don't think we will be able to actually "reduce" accident just because there are less human.

You've to see the distribution of whom create accident, example if 80% is caused by distraction then maybe you could reduce the number of accident by having self driving cars. But most of the current modern cars have many automatic detector that get triggered when a danger is detected.

We can say that these cars are expensive and as such people who buy old cars without this systems are more likely to cause accident.

The same people won't buy self driving cars due to the cost. So I'd argue that maybe we won't see much improvement unless a large percentage of people actually buy self driving cars

The technology is century away for mass distribution, same as cars nowadays are still not available in evey household around the world and there are plenty of countries driving super polluting cars taken from "first world" country

Ok, I think we're having 2 separate conversations:

a) What's the impact of self-driving cars at what point of distribution

and b) What's the distribution of self-driving cars going to be.

Regarding the impact: modern vehicles are getting better at minimizing the impact of accidents, and are starting to avoid accidents, mostly in the form of avoiding rear-ending another vehicle. But Self-driving cars are on another level there: They can recognize someone possibly running a red light, and act accordingly (not entering the intersection, evacuating the intersection quickly, etc.). They have sensors to continuously monitor their surroundings with a focus a human can't have, and modern vehicles don't bring the sensors for it because of the actions a human-driven vehicle can take are highly limited (Maybe a warning-beep, tightening seatbelts and prepping to fire airbags - but nothing in terms of avoidance. And you need a fairly fancy new vehicle for that). Additionally, also drivers of expensive / new vehicles crash. They have phones like anyone else, drink like anyone else, get tired or distracted like anyone else.

Regarding the distribution of self-driving cars: As I said, it's not feasible to assume that by the time you can buy or rent a self-driving car in the bay area, you'll also be able to buy or rent a self-driving car in Mogadishu. Additionally, ownership is one aspect of automated vehicles. Companies also aim for a service-type of business, where you basically take a cab - just without a driver (who again can get distracted, tired, etc.)

Now, if you say "we're a century away from having 50% self-driving cars in Somalia" - I wouldn't disagree. But the comment that started this discussion (and to which you said you have more or less the same opinion) questioned their present and future existence:

> Self-driving cars do not (and will not, if you ask me) exist

Maybe we're disagreeing on a misunderstanding?

I'm not seeing this with the current situation, given that everybody is aiming to sell the same amount of cars, but just self driving. That's how Tesla get the evaluation that it gets (total addressable market) and I can't see a fleet of robo taxi in the horizon yet.

So said, I'd agree if this is what we're leaning towards but again, is not what it seems to be going to be. If that would be the case, it falls under the "mass transportation" that I was referring to before.

> and to which you said you have more or less the same opinion

Well, they do not exists yet (Tesla even suggest not to run their car autonomously). Will not exists to the extend that we think they'd exists.

I think there would be space in which self driving will be probably adopted (eg. For example last mile delivery, robo taxi etc) but I can't see this being something that everybody must have. We can optimize the amount of cars around the roads by just sharing them. Yet all the current automakers + new one are addressing the problem (once again) but giving each and everyone of us a new self driving car. We need way less car, less pollution (electric cars still pollute, way less, but differently) more mass transportation systems. I can't see how this world can work with 7 billion people owning a car. Luckily there are countries where you can live without a car and where mass transportation is a thing.

So said, I was not the one writing that comment and I would've have said something like that either.

> I'm not seeing this with the current situation

It's what Waymo's is currently doing. So far, you only can get automated Taxis (in some regions) - you cannot buy an automated vehicle yet.

As I see we do agree that they will exist - and we also agree that they will never have 100% worldwide adoption. That would be a ludicrous assumption. Someone not buying a car now will not buy a self-driving car either. Someone never taking a cab will not take a driverless cab. I don't know how that was assumed or where that was ever claimed.
