The period of one's life during which one needs to drive the kids to rowing practice passes by fairly rapidly, in the course of the entire life. Structuring our entire society around the use cases of the very few isn't a good idea. Indeed, it would be highly beneficial to busy parents of busy kids if everyone else would get the hell off the road. Most of the people on the road have little reason to be there, other than that we've made it the default choice and outlawed everything else. If people could easily walk to the grocery store, or bicycle to the dentist, or ride a bus to their office, your trip to the boathouse would be ever so much easier.
