As we've seen on other threads, FSD is a waste of time because of the gremlins. There are loads of vids showing the car veering offline without warning!
Which means (in the UK) (a) because of the dreadful roadmarkings making FSD hard work and (b) having to 'follow thru' with your hands AND concentration - it is no different than driving it manually. Biggest waste of $5800 ever.
