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 read something a while back from a guy while wearing a T-shirt with a stop sign on it, a couple robotaxies stopped in front of him. It got me thinking you could cause some chaos walking around with a speed limit 65 shirt.

They're not reading speed limit signs; they'll follow the speed limit noted on the reference maps, like what you see in the app on your phone.

There's a lot of cars that check via camera too to double check, for missing/outdated information and for temporary speed limit signs.

Lots of places also have variable limit signs that get updated based on traffic, accidents etc.

Here in NZ those seem to all be marked on the speed limit maps as 100km/h even if in some places the signs never go above 80.

Ngauranga Gorge is one such location and I believe has the country's highest grossing speed camera.
