Without naming names someone has had the misfortune to receive a 90 euro French speeding fine for being a tiny bit over a 50kph limit. If not paid it escalates to a crazy 350 euros or so. Has anyone had a similar experience when they get back to the UK. It would be nuts to expect that they would take any enforcement action in the UK but if it is ignored presumably you get into difficulties the next time you travel to France? thanks.
