»War on war

We have a war on drugs, a war on poverty, and a war on terrorism, but why don't we have a war on single-occupancy vehicles?
Maps, 8-second maps, more maps, and advocacy are just the beginning. We should make transit free within the downtown -- Portland and Seattle already do. Federal regulations require a 25% farebox revenue contribution towards overall operating costs (and, in fact, most transit systems barely manage that!). Why not make MUNI free in the downtown area? Or across the entire system?
