Self-Driving Tesla Crashes into Wall Painted to Look Like a Road… Just Months Before Planned Robotaxi Launch (fuelarc.com)

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!

I have another idea: echolocation and laser measurement.

[–] towerful@programming.dev 4 points 2 hours ago

Echolocation is specifically audio based.
Lidar is a similar technique, but much more accurate and precise.
Project a grid of laser beam, read when the laser bounces back, you know the distance to that part of the grid.

I don't know the value of echolocation in this case, as I'm generally ignorant here, but it's straight wild to me that they went purely on visuals.

Tesla used to also have radar (and maybe lidar?) but they removed it as a cost cutting measure. If you ever see older videos of a Tesla slowing down or stopping due to a potential collision a few cars ahead, that's from before they switched to only relying on cameras. The collision avoidance was significantly better back then.
