How would you personally feel, and please answer honestly, if someone kept creeping up on you and they got struck from behind force their car into yours. Would you not question why they were so close causing you to be involved in an accident easily avoidable?
Where in the hell do you live where you managed to get rear-ended 4 times in under 5 years? I just feel bad for you!
I've 'dodged' being rear-ended twice in all the time I've been driving, and only actually been rear-ended once.
