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.
Maybe the lmgtfy would be a good exercise for you. Ford's BlueCruise, GM's SuperCruise, Rivian's Autonomy+, and Mercedes-Benz’s Drive Pilot all cost money.
Indeed and none of those work outside of (select) highways. Lucid also has DreamDrive, but it's fairly poor from what I've seen. BYD's God's Eye is in the news, and it isn't looking good either.
I'd love to see good competition in this space, but it seems Tesla has a healthy moat.
Maybe re-reading what I wrote would help you lmgtfy.
So are they part of the price of the car, or are they a subscription?
