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!

What’s cool is that Teslas used to have radar sensors, at least, but Elon removed them from production to save money. Even if you have a car from back then, the software no longer uses them and they’ll just physically unplug them the next time you have the car serviced, as it’s just a drain on the battery at this point 🙃

I didn’t realize EyeSight had different versions, on the Solterra it looks like it is indeed LIDAR.

My Crosstrek has the older dual camera setup for depth perception, it would not be fooled by a picture of a road on a wall… I’m surprised the Teslas are.
