Re: "...a [Lidar] blind spot low to the ground all around the car."
If there is a blind spot it is right in front of the bonnet. The lidar should have still seen the cyclist from far out. There is no info if the bike was carbon framed, I suspect not. If it was metal it would have been visible on the radar for miles. Similarly, most vis sensors are not actually vis, they stretch into near IR so there should have been no issue with the pedestrian having dark clothing and the car being driven dangerously for a human driver (to fast to stop within zone covered by headlights).
The only issue I can see is Uber. No other.
