"In smaller cities people are more willing to take lessons and finsish the course before the test, while in the cities people are more likely to drop out of the course and to try to take the test early," says Michael Axelsson, the vice-chair of the Swedish National Association of Driving Schools.
But what about a difference between two similarly sized small towns: Uppsala just north of Stockholm which has a pass rate of just 40 per cent, and Västerås over to the west of the capital city, which is on well over 60 per cent.
"Uppsala is a university city, where people are used to studying, so there are a lot mroe people not using the driving schools. Västerås is an industrial city, with a lot more people using the driving schools."
And regarding people travelling round to seek an easier driving test? Michael Axelsson says that most people simply don't bother.
