Real world Tesla camera based safety & self driving tech vs LiDAR

[tuminatr]

Interesting video I know many people have touted how well Tesla's self-driving and safety technology works but it's interesting to see a real world comparison and some definite weak points of their system.

Personally I've always felt that cars need both and this video kind of proves that.

This has generated some controversy, a lot of Tesla folks were complaining that Autopilot wasn't engaged when he crashed through the wall. You should know that he DID switch on Autopilot before crashing into the wall, but Autopilot disengaged itself less than a second before impact. ?

In response to criticism, Mark posted the unedited footage of the crash into the wall, you can see what happens yourself (rainbow road = Autopilot).



It is theorized that Autopilot will purposefully disengage right before collisions so Tesla can claim that Autopilot was disengaged at the time of the crash. Which is shady as f***, read more: https://electrek.co/2025/03/17/tesla-fans-exposes-shadiness-defend-autopilot-crash/ But regardless, the Tesla did not see the wall in time to stop which was the point.


Other than that controversy, I was surprised how good LiDAR performed in the fog and water. Can't wait to have this safety tech in my car someday, it could mitigate or eliminate almost all frontal collisions, even at high speeds.

Yea there is a reason he is trying to fire any agency that is looking into his companies and safety.

The LiDAR company Luminar sponsored the whole video, their logo is everywhere. You might say that's a conflict of interest since Tesla doesn't use LiDAR, but I'm sure people will see what they want to believe. The MachE gets along fine without the extra expense of LiDAR as well, but if you need a Tesla hit piece masked in safety outrage, this is your guy.

Tesla did purchase over 2 million in Lidar late in 1st quarter 2024. Largest customer.

Do NOT share this video with any Tesla fanboys. I made the mistake of sending it to a friend of mine, and he’s still stuffing my mailbox with angry rants and videos about how it’s all rigged, about how Mark Rober is actually a “democrat deep state operative”, trying to destroy the Musk/Trump agenda, something to do with transgendered people (which I couldn’t even understand). Those Tesla people are totally bat excrement crazy about this ?

I believe MB uses lidar in their cars that support limited Level 3.

No matter whether Auto pilot is engaged or not, it should stop when something is in its way. What's the point of having pre collision assist if it didn't even see the invisible wall?

i.e reason I did not buy tesla, my belief is camera + radar ( or lidar for future vehicles ) is best combo , we can not trust single system

Well then you should return your MachE because it doesn't use LiDAR.

The MachE uses visual cameras and radar, not LiDAR. Just like the Tesla.

Tesla doesn't use radar or ultrasonic anymore

I would be interested to see if they ran this kind of a test with other self driving systems currently in the market to see how they perform. This LiDAR used in the test is obviously a next generation tech

Well if the video creator in question says it, then it has to be true. Case closed.

I meant Lidar for future vehicles (I edited my post as well) , I know Mach-E has camera + radar,

Tesla removed radar long back it has just camera

 

[Maquis]

If you know how an autonomous system works, you can come up with a way to crash it. The question here is does this way to make the system fail correlate to any real-world scenarios?

I don’t know the answer.

"Respected YouTuber with years of science based content makes video of car's safety features failing in unusual circumstances and discusses the science behind it. This YouTuber, having never had any political content on his channel, is obviously part of a large political conspiracy to undermine Elon Musk. More RealNews at 11"
