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

[–] Valmond@lemmy.world 7 points 1 hour ago (1 children)

They are so expensive too! /s

Who would have known electronics gets cheaper all the time?? /j

[–] Viri4thus@feddit.org 3 points 1 hour ago

Except GPUs 😥

Elon removed the radar. Tesla cars never had lidar. What an idiot Musk.

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.

It was removed because it was giving false positives. They should have upgraded it with lidar but decided to just remove it.

[–] spankmonkey@lemmy.world 4 points 2 hours ago

Yeah, it might drive straight into a wall but at least it isn't returning false positives!

He did say lidar was "useless" though.

[–] echodot@feddit.uk 8 points 1 hour ago (1 children)

He's had humans don't use LiDAR so his cars shouldn't have to. Of course humans have a brain, and he's cars don't, but you can't tell him anything.

Human drivers also make automobiles one of the most dangerous ways to travel.

[–] Bazoogle@lemmy.world 1 points 39 minutes ago

I think it's also reasonable to say a human dying because of their own actions is different than a human dying because a big corp cut costs on safety features in an entirely autonomous car where the human has no ability to stop what's happening. (You can control them in current teslas, but they're working on cars without human controls as well)

He also said the government doesn't use sql.

[–] zenpocalypse@lemm.ee 2 points 33 minutes ago (1 children)

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.
