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!
Who was the idiot that removed LiDar to cut costs?
/s
Elon removed the radar. Tesla cars never had lidar. What an idiot Musk.
He did say lidar was “useless” though.
He also said the government doesn’t use sql.
Bahaha, what kind of a bizarre statement is that?
Was he trying to imply the government only uses spreadsheets and nosql DBs?
Or did he think it was necessary to point out that your average government employee isn’t writing their own SQL to grab data they need?
Someone said something he didn’t like so he blurted out the first ignorant thing that he thought of, as usual.
Even then, that’s not really correct. People grab data through sql queries all the time. Mostly because all the front ends are trash.
It was removed because it was giving false positives. They should have upgraded it with lidar but decided to just remove it.
Yeah, it might drive straight into a wall but at least it isn’t returning false positives!
It was removed because of supply chain issues.
That would make sense if they put it back after, but they didn’t
Tesla had camera+radar+sonar, and that wasn’t their own tech - they used mobileye EyeQ back then. When they switched to in house tech they gradually ditched the radar and sonar which made no sense to me. But at the time I saw their lead say in an interview that this is superior and I believed. not anymore.
they said doing so cut costs but obviously lidar/radar/sonar only gets cheaper over time, let alone the extra r&d costs because a vision only system is much more difficult to develop.
