> All that began to change in 1979. That year, New York’s Taxi and Limousine Commission changed its rules to allow medallions to be leased out for 12-hour shifts. The implication here is that the transferability of the medallions caused this big mess. We need a discussion of why medallions--which he says started simply as licenses--are being limited. This is the obvious question that is not addressed. After all, normal drivers' licenses and normal cars are not limited by the government in US.
