In Germany they have lower speeds generally and save all the speeding for the autobahn.
Personally I think many drivers need re-educating. The impatience shown by many is ridiculous.
Drove to work this morning (I did 3 hours of tough mountain biking last night and so was not up for cycling in) and a driver cut across in front of me at the last second as I was just entering the slip road to leave the motorway. So much for getting in the right lane, indicating when you reach the III sign.
I now wish I'd been naughty and put my foot down and blocked him so he had to stay on the motorway

the section from Stafford to Stoke is quite long and a round trip would have added 30-40 minutes on his trip.
