Hmmm... My major vice is speed. I never speed in a 20 or 30 zone by as much as 1mph, and I might drift a few mph over the limit in other zones.
But, on country lanes and motorways, on occasion I might exceed the limit by more than 1 or 2mph...
(But only when it's empty, I'm very familiar with the road, it's dry, and with no cyclists, ramblers, residents etc to annoy/endanger. I'm strongly of the view that any a**ing about should cause no danger to others.)
Oh, my other vice is that I turn into a driving instructor whenever my other half is behind the wheel...
