One thing this and the comments really highlight is how different driving styles are in different countries. I wonder how much this is responsible for traffic accidents? As an example: - In the US people aren't taught (or don't care about) lane discipline, where as in Europe you will make people very angry driving slowly in the inside lane [0]. As such undertaking is usually prohibited in Europe, where as it's allowed in most cases in the US. - If you are waiting to cross an on oncoming lane of traffic and someone coming towards you flashes their lights, in the Middle East it means "wait, I'm coming", where as in the UK it means "go ahead, I'll stop". [0] Italy is my favourite for this. People will come up behind you (doing 160km/h, while you are doing 130km/h and the limit is 110km/h :D) and start tailgating and flashing their lights until you move.
