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!
Radar doesn’t detect stopped objects at high speed. It’d hit the wall too on radar alone.
This has to be solved by vision and or lidar.
Unless your car is traveling faster than the speed of light, radar will detect objects in front of it. But yeah, I was trying to imply that for a complex system like self driving musk is a buffoon for relying on a single system instead of creating a more robust package of sensors.
They get filtered out and the car will not act on it because there is so much noise from stationary objects all around you.
The radar in all cars is used to detect moving objects and the change in velocity of those objects.
Radar will not prevent running into this wall at 40mph.
People can downvote me all they want, but that doesn’t change anything.
Only vison and / or lidar would stop for that wall at 40mph.
