I'm still learning to drive so I haven't came across much. Only thing that stuck out in my mind is when I was driving along on a main road and I was about to drive past a junction but some idiot was approaching the junction too fast. He just saw me and managed to brake just in time. That's about it really although it scared the shit out of me for like a second or 2.
we were distracting my friends sister who was driving and it was a red light and she turn around and was like half a foot away from the other car, sure it was scary at first but then we pissed our selfs laughing once we got home
