I feel an adult should be able to make the choice to wear one or not but it really pisses me off to see a car with kids climbing all over in the back yet the adults are sometimes buckeled in the front. I even see babies laying on the seat sucking a bottle. Some say "well I'm just going up the street" When my son was about 5 years old we were driving back to the house in my big 4X4 from Pizza Hut. Literally just down to the end of a residential street. I told my son not to worry about the seat belt we were only 1/4 mile from the house. This kid blows a stop sign causing me to slam on the brakes sending my son slamming into the dash busting his lip and nose.
