My brothers friend (hes 20) was driving like idiot until he almost killed himself and other friend. He was going about 100 km and tried to pass other car on the mountain, at night, on a turn, with double line. Guess what, a car came out of different direction. He was lucky because he had time to brake. My brother said hes not driving like idiot after that but im not sure. I drove with him once and it was really exciting but not worth it. By the way that friend that was driving with him is one of the best students in city where I lived in Poland. He got to one of the best colleges in Poland. It is unbielevable that he could get his whole future ruined by that idiot.
