Semi truck strap binder versus human jaw

People are so nonchalant driving along in their 3000 pound weapons. A friend of mine was killed when a young girl leaned over to get the soda (pop) she dropped. She came across the highway from the opposite direction, and hit my friend in the left quarter, driving him into a tree.
I've always said that the highway is the most dangerous place you can be, other than a battlefield.
3000 pounds?

a 2 seater perhaps
any car with enough size to be usefull will be in the 5000 pound range
