If only elon hadn't insisted on not using lidar or anything other than just visible light cameras
Yeah, pulling radar from the cars was the beginning of the end. Early teslas had radar, and that was what led to all of the “car sees something three vehicles ahead and brakes to avoid a pileup that hasn’t even started yet” type of collision avoidance videos. First, pulling radar was a cost cutting thing. Then Elon demanded that they pull out the lidar too, and that’s when their crash numbers skyrocketed.
They never had lidar, as far as I know.
The video literally shows it having lidar tho.
The lidar car in the video is a modified Lexus prototype (came with radar from factory, modified by a third party, with Lexus branding blacked out and replaced with the third party name)
Afaik at the moment there are no cars in the market that have lidar (waymo is adding lidar to cars that have only radar as stock)
Ah, gotcha, I was only half watching so I misunderstood. Thanks for the clarification.
well, the video is peak youtube, 19 minutes where the first 9 minutes are completely irrelevant, followed by 6 minutes of repetitive content, then the interesting part that made us click is just 30 seconds, followed by an irrelevant conclusion. It's more an ad for those two companies that lent the lidar than actual road safety test
Idk, as a reformed Disney nerd in my youth, I thought the section about Space Mountain was cool as hell, even if it was only tangentially related to the rest of the video.
Yes absolutely interesting and weirdly he put way more effort on the "irrelevant" part of the video (I don't think that the lidar cloud automatically becomes a 3d printable object, especially as perfect as shown in the video, with uniform and smooth rail tracks, usually that's a painstaking manual step)
I didn't think the video was suggesting it automatically became a 3D object, just that lidar was used to map out the ride in a 3D space.
I think some Chinese ones do (nio?), but definitely not tesla
