A YouTuber's homemade Tesla test looks like something straight out of a children's cartoon.

CrunchLabs founder and former NASA engineer Mark Rober put Tesla's Autopilot through its paces to see if it could detect the same road obstacles as a vehicle that uses LiDAR — a system that Elon Musk has previously called a "fool's errand."

The verdict? Kind of.

The automatic driving features of a Tesla car have been put to the test with a fake "Wile E. Coyote wall" by an engineering YouTuber, and it didn't go as Tesla CEO Elon Musk might have hoped.

Mark Rober, who has over 65 million subscribers on YouTube, tested the vehicle's autonomous cameras by driving at a screen with an exact replica of the road behind it, in the style of a Looney Tunes sketch. The car was unable to detect the wall, crashing directly through it.

Newsweek contacted Tesla for comment via email.

Mark Rober is perhaps the most successful science and engineering YouTube creator.

He has 65 million subscribers — more than Taylor Swift — and many of his videos have over 120 million views, surpassing the most recent Super Bowl.

Rober’s most recent release compares a Tesla dealing with various road issues with a test car with a Luminar LIDAR. He tests how both cars react to a dummy child in the road obscured by fog, water jets, bright lights and even a giant printed poster showing an empty road, as sometimes seen in the Road Runner cartoons.

Luminar Technologies Inc. shares surged on Monday after former NASA scientist Mark Rober test-drove a car equipped with the company’s lidar technology in a YouTube video and said it outperformed Tesla Inc.’s Autopilot feature.

In the video, which has drawn more than 11 million viewers since it was published to YouTube on March 15, Rober runs six tests assessing the lidar technology against Tesla’s system, which he said navigates using only “simple cameras” and image processing.

Can you trick a Tesla’s camera-based Autopilot system, which has been linked to hundreds of crashes, using simulated rain, fog? Will it barrel through a wall covered in an image of the road beyond, like Looney Tunes’ Wile E. Coyote slamming into the Road Runner’s fake tunnels?

Yes you can, according to Engineer and YouTuber Mark Rober’s testing. (Bonus: Rober also uses LiDAR to map Disney’s pitch-black Space Mountain coaster. )

The first wave of White House-ordered firings at the Federal Aviation Administration included employees who play important roles in the safety of air travel — despite the Trump administration’s assurances that no “critical” staff had been axed.

A Delta Air Lines flight from Minneapolis crashed and overturned while landing at Toronto Pearson Airport on Monday afternoon, with photos showing the plane with its belly up on the tarmac.
