Many cars are lidar,, but they use much stronger, bigger, and higher power lasers, on very expensive and precise rotator assemblies.

The L515 I mentioned was somewhat advanced at least for it's day because it used MEMS to steer its light source. That gave it leading class performance/size but it's still big and kinda hot-ish. Maybe we can keep scaling that kind of system performance to smaller sizes but even this package was pretty cutting edge & gave much better falloff than many competing systems, and was still largely an indoor sensor.
