Unfortunately, I disagree with you here. We should be fare, DD Pro is Tesla Free version of AutoPilot and no more. FSD is way advanced than DD Pro. It changes lane for you, drive on navigation. Smart Summon where you can bring the car to you from the parking spot, stops at traffic lights/Stop signs, and drives in Cities. The last feature is still under improvement but well engineered! If you have not experienced it, I would suggest you to watch some YouTube videos.
I have been on FSD beta since it was released last year. It's terrible at everything you just listed.
Lane changes occur far too often and for completely non-logical reasons. Like, you'll be one mile from your exit, and it'll want to move over to the passing lane. Or it'll come to an exit and fail to get into the exit lane until 30 feet from the exit. Or it will happily drive you into an HOV lane, even though you're not allowed in that lane unless you have at least three passengers.
And if two lanes are merging into one, have fun. The car will ping-pong back and forth between the two lanes trying to figure out where the center is.
I've never gotten Smart Summon to move the car more than 10 feet.
With the city driving, I have yet to complete a local neighborhood trip that involves more than one turn successfully. It has driven across three lanes of traffic for no reason, actively steered me into a cyclist in a bike path, stopped dead in the middle of a block for no reason whatsoever, and on and on.
Every time Tesla releases an update, I try it once, to see if anything has improved. I have yet to see meaningful improvement.
FSD sounds great on paper. In practice, it's a complete and utter mess. And it's downright dangerous. Anyone spending $15k on it should have their head examined.
The YouTube videos you refer to, that people keep telling me prove FSD is great, are full of instances of the driver going "Whoops" and having to take over.
I'll be much happier if Lucid takes its time and releases dream drive features one at a time. When they actually work.
