Hey Everyone,

Stumbled upon this , was looking into proximity sensors and how they are used in automobiles found this https://www.derf.com/an-overview-on-proximity-sensors/ which explains the different types of proximity sensors. I am curious though which type of used in autonomous cars?

Any help would be great !
