Which part of Europe? According to everyone I know in Sweden (including myself) it is really frowned upon to do that. If you enter without being sure that you'll be able to exit in time you're a massive jerk.
From the UK here too, I've been living in Norway for 30 years now and Norwegian drivers only really started to get the hang of roundabouts and pedestrian crossings (zebra crossings) about five years ago. In the Drammen area at least.
Lost count of the number of times I have been almost run down on pedestrian crossings but it's much better now than it was.
One thing that is very good here is that everyone gets out of the way of emergency vehicles very promptly.
I work with a guy who got a fine and points for not stopping at a zebra crossing in Holmestrand, and the person the police meant he should stop for wasn't even crossing. Apparently the rule is that you should stop even if they look like they might cross.
My biggest pet peeve is that many people don't seem to understand slip roads and tailgating is rife. Also that patience is a virtue, if I'm in the middle of a 3 point turn on a country road then don't drive around me, just wait the 4 more seconds it will take me complete the maneuver. And parallel parking, don't get me started.
