> how is it possible for a phone to have LiDAR

Just like you can have a 50MP camera sensor in the phone: it works? Sure. Is it sufficient to capture the Moon (heh) or something 50-100 meters from you? Not at the quality and performance of professional equipment.

Sure, you can have a matrix of iPhone LIDARs but whould they works at sufficient speed, accuracy, at +40C, at -35?

Why should they need to in a L3 system ?

All L3 systems only operate under known easier conditions. The self driving could turn off in unfavorable conditions .

My car’s lane centering switches off if there is rain or snow obstructing sensor .
