4 wheelers atv safer then 3 wheeler atc?

why do people always say 3 wheelers are so dangerous. i have been riding them my hole life and have nvr been hurt but every time i get on a 4 wheeler i ether end up in a tree or roll it. i have actually sworn off 4 wheelers since my last incident. i think the extra wheel just make ppl over confident which is nvr a good thing.
