In the piece — titled “Can You Fool a Self Driving Car?” — Rober found that a Tesla car on Autopilot was fooled by a Wile E. Coyote-style wall painted to look like the road ahead of it, with the electric vehicle plowing right through it instead of stopping.
The footage was damning enough, with slow-motion clips showing the car not only crashing through the styrofoam wall but also a mannequin of a child. The Tesla was also fooled by simulated rain and fog.
Everyone and their dog uses radar for distance sensing for the adaptive cruise control. You take the same migh speed sensor and use it for wall detection. It’s how the emergency stop functions work where it detects a car in front of you slamming on the brakes.
