I don't care
I have been driving for nearly 20 years and I don't care about 3 point turns, U turns etc etc as I to be honest I don't really need to use them however what I do care about it the muppets that don't understand the speed limits i.e. doing 20 in a 50 or 30 in a national speed limit area when the signposts clearly state the speed. What I most hate is the people that do 40 on the motorway before they exit or enter at 40. Driving to slow is not only dangerous but should be drummed into the new drivers as such and to be fair should be informed to the older drivers too as I swear it's in the highway code as being dangerous.
