automobile accidents is the first non-disease on the list, so i think the original claim is correct, even if the lack of statistics blow it out of proportion.

IMHO, people underestimate the risk of death and injury from driving. while inciting fear is not really a good educational tactic, i can understand the frustration. my response is to wear a helmet whenever i go for long highway rides. and to avoid transportation as much as possible. (*obviously not for everyone)

edit - disease effects a different crowd than motor vehicles, which i think is part of the risk/cost evaluation.
