A big way to eliminate transportation is to legalize the construction of housing and the operation of businesses in and near cities, then allow people who commute for an hour or two to move so they don't have to commute. This is impossible, because we (boomers) have decided that it's important for our society for local governments (boomers) and sometimes residents (boomers) to have veto power over housing construction and the ability to delay business openings by years.
