I also wonder if the smaller sensor size on phones contributes, since the energy is being focused onto a smaller spot.
Either way, for that to happen he was filming the LIDAR while active, for a decent amount of time, from right next to the car. I assume under normal conditions it wouldn't be running constantly while the vehicle is stationary?
Laptops aren't generally being used in the same areas as cars though, so you wouldn't expect to see as many cases involving Windows Hello compatible laptops/cameras.
