In reply to GrahamD:
So comparing leaving London at midday, and arriving in Paris in the middle of the following day isn't comparable?
The difference wasn't small, it was astonishing. Similarly Riding country roads in Belgium, Italy, Spain, France (I'll exclude Switz as it's mainly mountainous) is a real pleasure compared to riding country lanes the length and breadth of this Country.
Roads which are quieter and have good visibility have never been the problem in the UK either in most cases, the problem is when drivers force through passes against oncoming traffic, fail to make room, get impatient on a hill and hurl abuse etc.
