I can tell you the real reason: Cameras are cheap for the amount of stuff you can kinda-sorta manage with them. That’s literally it. There’s no other 4D chess game of data collecting or anything else. They’re cheap to add and integrate, and adequate for object detection in typical scenarios. No need to worry about the shape of the bumper or paint effecting the radar, no need to have a bunch of individual ultrasonics integrated into the bumper and the associated wiring/labor costs.
I worked with them, and there were numerous times where they came to us asking for new sensors because their cameras were too shitty for what they wanted to do, then once they got a quote, they miraculously didn’t need them and figured it out. It happened with corner radars on the Y, it happened with them removing the front radars on everything, and it happened with the ultrasonics.
They bet it all on cameras as a lie to consumers and defraud investors that their cheap shit-boxes would be income generating Robotaxis. Even worse, their own engineers had hard data showing that removing the radar would directly result in pedestrian/motorcyclist deaths, but they had to keep those bullshit production numbers going, so they took them out and it’s directly resulted in dozens of likely preventable deaths.
Anyone who’s ever worked with Tesla directly knows they’re an absolute fucking nightmare, and even compared to the shitshow of GM or Stellantis, the absolute blatant disregard for human life at that company is disgusting.
Mood. It’s a scary fucking time to have this realization, and I’m really not sure what I’m going to do either…
