Idk. The non-compressed version makes it seem like the truck was very visible. I think any driver paying attention would have at least applied some braking.

Yes, and your human eyes have far better dynamic range than these cameras. Plus, I could tell there was something in the road early on despite the truck not being illuminated, because I saw the oncoming headlines disappearing behind an obstruction.

Really shows how Tesla has probably made a big mistake going all-in on camera only vision. And their vision system couldn't make the inference of an obstruction based on the oncoming headlights.

Lidar would have been able to detect this easily.

How did they even justify the use of a camera-only sensor system for low-light conditions? At least the radar sensors had some complementarity with visible light sensors but they decided to get rid of those too.

I watched the compressed version before seeing this non-compressed version, so I was primed to expect the black truck.

Maybe I would have stopped. Maybe not.

Derailing, I wonder how hard it would be to have emergency lights on a vehicle that trigger after an accident.

This is already present on many cars. After decelerating fast the alarm lights come on.

For instance:

You have to have at least one road flare in your car in Japan or it won’t pass inspection

It seems like it wouldnt be hard to have the hazard lights start blinking if the airbags deploy.

I think the issue is that those lights are on the main power circuit, which shuts down if the user turns off the car.

That appears to be what happened here, I don't see running lights or anything. I think the person turned their truck off.

I honestly don't know if you're supposed to shut your car off after an accident to lower the fire risk, or leave it on to make the car more visible.

Two issues that come to mind are (1) keeping the lights on while otherwise shutting off the vehicle and (b) ensuring that the lights don't all get smashed to bits in the accident.
