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.
Right, those were the failures that really matter, and Rober included the looney tunes wall to get people sharing and talking about it. A scene painted on wall is a contrived edge case, but pedestrians/obstacles in weather involving precipitation is common.
I think it does highlight the issue with the real world. There will always be edge cases and situations that lead to odd visuals.
