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!
All these years, I always thought all self driving cars used LiDAR or something to see in 3D/through fog. How was this allowed on the roads for so long?
They originally the model S had front facing radar and ultrasonic sensors all round, the car combined the information to corroborate it’s visual interpretation.
According to reports years ago the radar saved Tesla’s from multiple pileups when it detected crashes multiple cars ahead (that the driver couldn’t see).
Elmo in his infinite ego demanded both the radar and ultrasonics be removed, since he could drive with out that input so the car should be able to… also it is cheaper.
tesla uses cameras only, i think waymo uses lidar.
Most non Tesla brands that have some sort of self-driving functionality use lidar and/or radar. I’ve got a BMW iX and as far as I know it uses cameras, radar, lidar, and ultrasonic sensors.
I remember reading that tesla only uses cameras for it’s self driving. My 2018 Honda uses radar for the adaptive cruise so the technology exists, musk is just an idiot.
Does it? My 2023 model throws a shit fit if it’s cold and I assume the camera covers are iced over.
It probably has cameras as well, for lane guidance etc.
My Mazda complains if the windscreen is dirty for the same reason.
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.
they generally do
