Does the Tesla always activate its brake lights when slowing down? (I have an EV6, and I don't even know if brakes lights come on when I'm using regen as opposed to the brake pedal) When I'm driving and traffic is stopped ahead, I used to always brake not because I had to, but as an indication to the car behind me.

Yes, but it depends on the speed you are going

Comparing Tesla to the US incident average is a neat way of ignoring that high-end electric vehicles are not driven by the US average driver, in average situations. The driver (or should we call them executives, in self-driving cars?) is likely to have much more to do with the statistics, that the car.

The reason for that difference should be evaluated then. Is it an income thing? Car cost thing? (compare stats to non-Teslas in the same group) Does Tesla's marketing create a false sense of confidence in the car's abilities? Does the UI distract? Numbers can lie, but in general, I think the data is out there to support or reject the "fake news" narrative.

Yes, brake lights are illuminated under any deceleration above a certain threshold, or application of the brake pedal.

Yes, as soon as you hit regen your brake lights come on. I tested this with a Honda Hybrid a long time ago to make sure. If your car has a diagram somewhere that you can display while driving you will actually see it on the display.

It's not even comparing Tesla to US incident average, that would be an improvement. It's comparing Tesla in situations where people are comfortable activating Autopilot to US incident average.

The absolute easiest miles for a luxury vehicle vs all miles for all cars.

Thanks for asking this. I've never thought of the implications of re-gen braking when slowing down!

Searching around seems inconsistent across different brands/models/model years (eg Bolt behavior changed recently). As one pedal driving becomes more prevalent might be something in need of a standard.

For Tesla Model Y:

Autopilot does emergency braking for nonexistent obstacles. I'm sure it's contributing to rear end collision risk. I stopped using it for this reason.

Nothing is stopping you from looking at the Q3 2022 Autopilot vs Q3 2021 numbers, the others are nice for reference

Given that per the NHTSA 29% of all accidents are rear end collisions, I don't think the 35% number is meaningful, given the small sample size. Also: Tesla has always been clear about their definition of "crash", it hasn't changed since they started reporting years ago.

> Also: Tesla has always been clear about their definition of "crash", it hasn't changed since they started reporting years ago.

But it says specifically it does since Jan 2023 and they've retroactively adjusted their previous reporting...
