Let's hear it for Finland:

Finland's speeding fines are linked to income, with penalties calculated on daily earnings, meaning high earners get hit with bigger penalties for breaking the law. So, when businessman Reima Kuisla was caught doing 103km/h (64mph) in an area where the speed limit is 80km/h (50mph), authorities turned to his 2013 tax return. He earned 6.5m euros (£4.72m) that year, so was told to hand over 54,000 euros.

The scale of the fine hasn't gone down well with Mr Kuisla. "Ten years ago I wouldn't have believed that I would seriously consider moving abroad," he says on his Facebook page. "Finland is impossible to live in for certain kinds of people who have high incomes and wealth."

In 2002, an executive at Nokia was slapped with a 116,000-euro fine for speeding on his Harley Davidson motorbike. His penalty was based on a salary of 14m euros.
