> lane/speed maintenance that pretty much all car makers can do now
What car can I buy in the US today that's as good as the latest fsd?
So many cars come with lane assist and adaptive cruise control. You can google those terms for yourself. I don't bother with lmgtfy requests. You're a big boy/girl, and teaching you to fish it much better effort. They also don't cost an additional $10k on top of the price of the car. They are just part of the price of the car.
Literally every non-budget brand (and even some of the budget brands) offers automatic lane keeping with traffic-aware cruise control somewhere in their fleet. It might only be on their flagship vehicles, and possibly only on the top trims, but you're living in a Tesla-decorated cave if you think those are still Tesla-only features.
On a Tesla, it's not even an FSD-specific feature. Autopilot does it.
