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.
Whether lidars are reliable enough to run on autonomous cars has nothing to do with whether they are cost efficient enough to run on vacuum cleaners though. The comparison is therefore completely irrelevant. Might as well complain that jet fighters don’t allow sharing on Instagram your location, because your much cheaper phone does.
