Mark Rober just set up one of the most interesting self-driving tests of 2025, and he did it by imitating Looney Tunes. The former NASA engineer and current YouTube mad scientist recreated the classic gag where Wile E. Coyote paints a tunnel onto a wall to fool the Road Runner.
Only this time, the test subject wasn’t a cartoon bird… it was a self-driving Tesla Model Y.
The result? A full-speed, 40 MPH impact straight into the wall. Watch the video and tell us what you think!
The point of the test is to demonstrate that vision-only, which Tesla has adopted is inadequate. A car with lidar or radar would have been able to “see” that the car was approaching an obstacle without being fooled by the imagary.
So yes, it seems a bit silly, but the underlying point is legitimate. If the software is fooled by this, then can you ever fully trust it? Especially when sensor systems exist that don’t have this problem at all. Would you want to be a pedestrian in a crosswalk with this car bearing down on you in FSD?
