Most probably because it has a radar that the Tesla lacks. That means your car has two sources of truth and can very efficiently and quickly make an informed decision about whether or not there's anything in the way.
- hbarka 8mo agoMy Model 3 has radar. It’s no longer functional and just a useless appendage. Until 2020-21 all Tesla had radar but Musk directed Tesla to disable the radar from the software stack, nerfing this hardware on tens of thousands of cars. Why? Because he staked on camera-only and to find out there’s still radar fusion would be against that. The real truth is probably they were derisking the part cost (during Covid) and the development timeline to improve the radar integration (after dangerous false braking incidents). It was wonderful when it worked, especially the time-of-flight ability to sense a decelerating car ahead of the car ahead of the one in front of you. When it didn’t work the Navy Seal guy driving and watching a video was the first statistic. The real Tesla engineers must be in all kinds of frustrations getting whipsawed by their chief engineer-designer-physicist-scientist-government economist-savant but probably the stock options assuage that. Lastly Tesla still doesn’t have real birds-eye view / 360 surround view for parking. It’s year 2026 and even cheaper cars have this.
- groos 8mo agoMy 8 yo M3 has radar and it still is active since the yellow radar symbols light up when passing by obstacles. It's also used to figure out obstacles in the front and back and if disabled, the relatively poor cameras on my car would not be able to figure out the distance to the next car in the front.
- hbarka 8mo agoThat’s your ultrasonic sensors. The millimeter-wave-radar was front only and designed for far focusing out front.
- kube-system 8mo agoYes, for parking obstacles. But their vehicle probably also has radar sensors in the rear corners of the bumper for cross-traffic alert.
- philistine 8mo agoMy shitty Kia Niro has a UI element that indicates anytime it detects an obstacle in my blind spot. My side mirrors even have a red light that also tells me it detects something. Tesla doesn't do that?!
- kube-system 8mo agoApparently they do it via camera
- gwbas1c 8mo agoI don't think my 2018 Model 3 with enhanced autopilot ever used it radar for lane changes. As I noted above, it would just drive with the blinker on and a clear lane.
- philistine 8mo ago> The real Tesla engineers must be in all kinds of frustrations That's a very Hacker News point of view, that *of course* engineers have the correct opinion and attitude and are merely suffering under the boots of the real incompetent and nefarious. Engineers at Tesla are wholly complicit.
- theshrike79 8mo agoIn this case the dude giving the order is the richest man in the world, hopped up on ketamine and a habit of just YOLOing stuff. A single engineer telling him that LIDAR and radar is superior to camera-based systems isn't doing anything except getting said engineer fired.
- cogman10 8mo agoIt's clearly not, but cameras are cheap and Tesla is excellent at cost optimizing their cars. Elon was pretty good at film flaming that somehow imprecise cameras were actually somehow superior. There's a reason Waymo is doing actual level 4/5 driving while Tesla remains at 2.5.
- indolering 8mo agoThey 100% make excuses for the guy and buy his bullshit. Nothing screams cognitive dissonance like believing that Elon had no idea that his Nazi salute would look like a Nazi salute!
