The right question to ask is how many rear-end collisions does it produce and how many accidents it prevents.

If it infrequently phantom brakes (especially when there is no vehicle behind - an AV can sense that), that doesn't cause any collisions, this might be optimal behavior, given the current level of technology.

Agreed. People seem to think that anything that allows for any accident at all (irrespective of frequency or severity) is better than the status quo of 40k fatalities per year, which is pretty wild considering how otherwise rational this forum tends to be.

This comes down to the actual risks. The real question is has it actually caused any accidents?

With random hard braking the question is not if but when and how often.

I'd say the question is whether we should tolerate cars with what you could call undefined behaviour. Imho we shouldn't.

Why do people think the goal is “perfection” rather than “better than the average driver”? If Autopilot is 10x safer than human drivers, we would have to be stupid not to mandate it much less tolerate it, even if it’s crash rate is non-zero. Human drivers kill 40k people a year in the US alone—that’s almost twice as many people as all homicides combined.

So, any data to back this claim?

And has it prevented any?

While the erratic behavior of Tesla’s autopilot might cause other drivers to be more cautious are them, I don’t think you should count this in Tesla’s favor. Imagine if every self thriving car company started adding code to scare other drivers, that would definitely have unwanted side effects.

Teslas have one crash for every 4.31 million miles driven with autopilot engaged versus one crash per every 480k for non-Tesla drivers, so autopilot is averting almost 90% of all crashes. There’s no evidence at all of any “it scares other drivers into safety” mechanism, which is to be expected because such a mechanism seems absurd on its face.

This article is specifically referring to fantom breaking rather than overall performance of the system.

I know I personally have started to stay further from Tesla’s when possible on the road because they behave strangely. But the same applies to other cars which do this odd weaving from side to side within their lanes presumably because of poorly implemented lane keeping systems.

As to accidents rates, Autopilot shouldn’t be compared to overall driving accident rates when it’s not being used in all situations.

No, I mean by having this feature of lane keeping and cruise control saved lived overall.

Probably. Tesla Autopilot gets in about 90% fewer accidents per hundred million miles than US drivers. It would be shocking if this didn’t manifest as lives saved.

Just to be clear, you want to make TACC + lane-keep illegal? Because that's what the comment is taking about.
