Re the lack of police doing traffic enforcement, it is actually quite an interesting topic. In Europe it would seem the police are increasingly having to focus on other things ( Islamic terrorism, continually increasing crime from immigrant or transitory populations, etc [not a political statement, just the reality of the new Europe!]) and this seems anecdotally at least to be decreasing the police presence on the road. A week ago I drove from London to southern Switzerland in my 993 4S, about 11 hours of driving, and did not see a single police car on the way. I am ok with the no police cars btw and I must say the French auto routes are just wonderfully well sited and not busy at all so as long as you are reasonably watchful, you can keep speeds up at levels which gets you on an average basis above parts of Germany.
