Lane change on the interstate is fine, but for city/road nav it can be really bad. There's been more than a few occasions where telsa will try and put me in the wrong lane (even on long and well established road) which would ultimately force an unintended turn. If I'm not babying the system, the car will try and cut off whoever is behind me to follow the route.
Frankly, I don't trust it because of these sorts of problems.
I had a lot of years with Comma AI before. There's no other consumer system on the planet that is close to FSD. lane assist's and adaptive cruise control are getting better with legacy manufacturers but they're still so far off.
Not the problem. Like I said, it's getting into the wrong lane and then cutting off people when it realizes it's not where it should be.
That's not a "It's not driving how I would" problem. That's a "It's creating a dangerous situation because of poor mapping data/bad route decisions" problem.
I typically drive with FSD on, but I'm quick to disengage because it's really not uncommon that the system will try and put me in an obviously bad situation.
