I would never have the car set my speed by road signs. Too many mistakes. There’s a slip road on the M60 where they have a temp 50mph speed limit. The car picks this up everyday as I continue on the M60, so would be slowing me down in the fast lane for no reason if it had the chance. Also I find that if I have the ACC set to say 70 and come up behind a slower car say 55 in the slow lane, if I have to sit behind it before a can pull out due to heavy traffic, when I find a gap and move right, it takes the car an age to accelerate back up to 70. Anyone else had this? Is it configurable in settings? On a busy motorway it just scares the life out of me.
