“You are about to hit a solid object. Stop.” Why can’t we solve the most basic use case? We don’t have the sensors and it’s all done with cameras?

It’s a solved issue, but Tesla doesn’t use LIDAR so it will never be solved for them.

  But they use Radar and ultrasonic sensors, which should be enough (and even better, since LIDAR doesn't work in fog).

    They doesn't seem to build any 3D scene. Their radar doesn't seem to be sweeping in any axis, so it is good only for detection in narrow sector along the road surface. This is in particular was stated as the reason behind that case of driver being decapitated by driving under the road crossing semi truck. Their ultrasonic i'd suppose have similar fixed direction functionality and probably for much smaller distances.

      Binocular vision can do it just fine under most circumstances. Subaru Outback with Eye Sight is better than AP for this by far.

  Why not? Isn't this the solution? I do remember hearing a while back that the cost for a lidar rig was around 5k, but given the fact it would save lives this seems like an obvious move?

    Musk has stated publicly multiple times that he believes autonomous driving can be solved without LIDAR and directed the team at Tesla to not use it. https://www.theverge.com/2018/2/7/16988628/elon-musk-lidar-self-driving-car-tesla https://www.theverge.com/2018/2/7/16988628/elon-musk-lidar-s...

Too many false positives; sensors would only be usable for cars that moved a few km/h at most. Even if you're driving normally, various other objects appear in your path all the time.

  So don’t ship it then? Honestly, it seems like a fairly fundamental feature, doesn’t it?

  Sounds like a bad excuse to me

  And yet the forward collision warning on a lot of inexpensive cars like Hondas would have warned the driver and then hit the brakes in this situation. We clearly don't have an epidemic of cars with forward collision warning systems slamming on their brakes for no reason, so those systems must be able to deal with the false positives somehow.

We? We have already solved it. They (Tesla) hasn't.
