Traffic crashes kill more people each year than bullets from handguns. According to statistics, traffic crashes are a leading cause of death worldwide, claiming millions of lives annually.
The force of impact from the crash kills them.
A lot of things, but I'm guessing you were looking at fun facts and saw that donkeys kill more people than plane crashes. However, that seems to be an urban legend. It is far harder to find an accurate statistic for the number of people killed annually by donkeys than it is for those killed by plane crashes for obvious reasons, so a conclusive answer cannot be given, but it definitely seems as though that little "factoid" is very much untrue. A decent amount of people are injured by donkeys or killed as a result of accidents related to donkeys (mostly car crashes involving a donkey) but the number of people actually killed by the donkey itself is extremely low. Sorry to ruin that fun fact for you :)
Yes. Smoking kills more people than car crashes, suicides, alcohol, murders, illegal drugs and AIDS combined.

Neither the car crashes have a cumilated to match the amount of deaths per year with bullets from hand guns.
