One of my biggest concerns about Tesla's vision based approach is that it appears to be entirely about cutting costs. Nothing about it says they actually think it is superior; the cameras on a Model 3/Y are mediocre. They were mediocre the day the Model 3 was first released. If you were going to rely on a vision system in a serious way, you'd at least invest in better camera tech. Hell, Subaru EyeSight has a significantly better camera setup, last I checked, and who looks to Subaru as a technical leader?
Someone else said it here on HN, and I think they're absolutely right -- Tesla is all about vertical integration, and this is preventing them from excelling at anything other than saving pennies. A good part of why the new EV competition is doing everything better is they didn't roll their own tech. They bought packaged solutions from companies that only do one thing, but do it well.
FWIW, the Subaru system is fantastic — I use it daily and it’s very predictable and literally never been dangerous. And works really well in stop-and-go traffic!
It’s not FSD, but if you use it as a driver assist, it takes a giant amount of burden off of driving in traffic. Even on a busy highway that’s going somewhat fast, it’ll just follow the car in front of you. And truly, it’s never once been dangerous.
Only catch is that it can’t “see” very long distance — if you’re going 70mph and there’s a stopped car in your lane, it probably won’t stop (at least, I wouldn’t test it!). But again, it’s driver-assist and not FSD, so you’re still expected to notice that. And within its limitations, it is really exceptional.
On the contrary, you can hear Andrej Karpathy explain how other sensors produce noise & are too low bandwidth when compared to vision. Other full self driving systems will probably follow suit & get rid of impossible to calibrate lidar systems.
How are the cameras mediocre? Do you want even higher resolution cameras? This would cause compute turmoil.

have you driven a tesla autopilot at night in heavy rain with no visibility of the lanes? I did, I was amazed at how good it was. I couldn't see lanes but it did and judging by the picture on the screen it saw them very well. More pixels doesn't mean better, same as more ram doesnt mean better (iOS example).
I have even earned the dubious honor of having been pulled over for suspected drunk driving because I used AP on a trip home from my MIL's house after Thanksgiving dinner. I was amused by how much trouble AP was having with mild corners on I-5, the state trooper behind me was less amused. Well, at least until he established that I was sober, then we had a good laugh about autopilot and he gave my kids sticker badges. A happy ending for everyone but I didn't activate AP again that night.
Maybe the problem was that it was clear and dry? Ya think it would have been better with some road spray on the cameras?
Subsequent to that, I ended up abandoning AP altogether because it was so jarring when it would decide an overpass looked like something it should slow down for. My wife suggested that she'd be happier if I just used my foot for the accelerator. For some reason we still ended up buying another one, but after the phantom braking on day one (empty freeway, overpass, apparently this is very much now "a thing"), I guess I'll just skip AP before even starting. I wonder if I could ask Tesla to deactivate AP altogether so I could have traditional cruise control?
