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!
Back when Elon made avoiding LiDAR a core part of his professional personality, it was fairly expensive. But as any tech genius can tell ya, component prices drop rapidly for electronics.
Now, radar is dirty cheap. Everything has radar. Radar was removed from Teslas. A radar sensor for my truck is $75, probably much less at scale orders.
LiDAR sensors cost anywhere from $500-$1,500 for a vehicle of this type, near as I can tell (this type being Level 2 autonomy rather than something like a Waymo. A well-kitted out self-driving vehicle has 4 LiDAR sensors).
Here is the LiDAR module currently used on the Mercedes S-Class, it’s $400 used: https://www.ebay.com/itm/285816360464
It’s a hideously small cost-savings in 2025 for a luxury vehicle like a Tesla. Any rational company would’ve reversed course after the first stationary-object-strike fatality. Tesla is not a rational company.
