Yeah, cuz spike free tires hasn't caused over 80% of all car-related deaths... Do you even have a car?
4x4's are heavy as hell (usually). And if they start sliding, they won't stop.
The tires are usually never the problem. Most of all accidents are caused by human fault. This includes driving when and where you shouldn't, so I can't see many ways to blame the tires. The same applies to 4x4s (on the weight-issue).
Oh, and I don't own a car, but I drive regularly with my father, even when the ice one the road is slick as a mirror, so I do know a bit about driving safely, yes. I do not say, however, that I'm better than anyone, but I can drive safely.
