Around here it is quite common to come up behind a queue of ten to fifteen cars travelling at 15 to 20 mph following a cyclist. If the leading car cannot bring him/herself to overtake the bike you are stuck because everyone following is nose to tail. Even without cyclists involved the top speed of all motorists seems to have become 40 mph..... No indicators until the steering wheel has been turned. People trying to park nose first in a space that clearly will only be accessible by proper parallel parking. There is very little evidence of anyone having been taught any driving technique at all. I think the cars have got too big for people to manage.
