Currently, it only uses the ultrasonic sensors which is why it needs objects each side to guide it in - probably not the best solution if you defensively park away from other vehicles.
Its actually a bit worse than that. There are a number of trickly charging spots in my office. Mainly obscured by concrete columns jutting into the space. Tried autopark and it almost hit the column:
I usually park slightly diaganaly there as the space is wide except for a narrow entrance.
NOA:
What I noticed on my commute, not all dual carriageways (with at least 2 lanes to allow overtake) will engage NOA. Basically Autopilot will not suggest overtake or lane change to you, NOA will. And even when NOA suggests a lane change to overtake, you still have to confirm (irritating). And of course lane changes are performed by a nervous learner.
So it still goes as others have said:
NOA says change lanes

Basically useless for agressive overtaking of any kind. But if you are on a long roadtrip through France, doing 130 and overtaking lorries doing 90 it's probably great. Especially since it checks the blind spot for you.
So if you have a chain of cars in the overtake lane on the M25, forget it... It will not merge unless you have a 3-4 articulated lorry sized gap.
Largely unrelated, but also noticed the new speed sign recognition doesent work on temporary average speed signs... Which is kind of the main use case for me...
