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.
False positives. Most like it detected something was off (parking sensor detected something for example) but doesn’t have high confidence it isn’t an erroneous sensor reading. You don’t want the car slamming on brakes at highway speed for no reason and causing a multi car pileup.
