In my household, besides driving to work (15miles and 6miles), there are mostly short trips: grocery shopping 1 mile, post office 1/2 mile, gym 1/4 mile, gas fillup varies but about 1 mile avg, other shopping 3 miles, movies etc 5 miles, eating out usually within 5 miles, dropping the kids off to school 1 mile. I guess it depends on how close everything is to you. The more rural you are, the further you have to go for everything. For people in a dense urban environment (and more likely to have accidents) the average driving distance must be really short.
