"Oh Shit" moments...

Just back from a week cycling around Normandy, only to learn of the "priorite a droite" rule when I got back. This explained a variety of "oh shit" moments that happened, people pulling out without looking, stopping on roundabouts, etc. It strikes me as the most illogical road rule I've heard of.

Had to intervene when my buddy was having a bust up with a taxi going round the Arc de Triomphe. Not the best place to discover the archaic quirks of foreign road rules.
