I was watching The Dark Knight after a long time and I noticed one scene where Two Face goes after the people who helped Joker kidnap him and Rachel Dawes. So he is sitting in a car with the gangster. They have talk and Two Face flips the coin. The clean side comes which means the guy is saved, but when he flips the coin for second time, destroyed face comes up. So Two Face says that the driver isn't lucky and shoots him.
The exterior shot shows the car flipping in air and crashing. How did Two Face escape the accident? Also, even if someone manages to escape such an accident, he would be badly injured. In case of an already-injured man, this situation should have escalated very badly.
