Of course you can die by getting hit by a car....that's kind of a silly question --- how much does a car weigh compared to a person -- even a BIG PERSON? Do you read the news at all and how old are you?
I'm sorry this happened to your friend. You friend could also live.....
Depends where you get hit and how fast the car was going. Also if the glass broke andgot into you, if bones were brocken, etc. I hope your friend will be okay!
