Tesla does not use lidar, only regular cameras.

Tesla used to use radar and camera combo. Has this changed? https://www.tesla.com/en_AU/blog/upgrading-autopilot-seeing-world-radar https://www.tesla.com/en_AU/blog/upgrading-autopilot-seeing-...

Any car with distance sensing cruise control or collision avoidance at least has some kind of forward looking radar tech, right? So it should at least be able to panic-break when noticing the mistake? It looked like the car had gone full speed into the barrier.

  Tesla has this radar tech but they get some confusing data sometimes so they decided to put code to ignore some of the detections https://www.tesla.com/blog/upgrading-autopilot-seeing-world-radar https://www.tesla.com/blog/upgrading-autopilot-seeing-world-...

It has radar too, I think. But this seems like the hardest thing for radar to see. Moving cars are easy to distinguish from the ground because they have a different doppler shift, but a stationary object does not.

  No, Tesla mentioned in a blog posts that the system gets confused by many static objects like the things above the road, so they have some code to ignore them. They detect the objects but have issues identifying them https://www.tesla.com/blog/upgrading-autopilot-seeing-world-radar https://www.tesla.com/blog/upgrading-autopilot-seeing-world-...

    By no you mean yes? The point is that sudden braking of the car in front is easy to detect on radar, but distinguishing static objects which you must avoid from the many which you need not (signs, trees, cat's eyes, gravel) is very difficult.

      Sorry if I was confusing, Tesla hardware seems to detect the static objects(like cans on the road) but they put software to filter some objects out, I hope we will get some logs of the crash (can people pull the logs from their Teslas or are DRMed?) If we had the logs we would know if the car ignored the object or the hardware it is just blind for some objects.
