Robert Prather links and excerpts some calls for High Occupancy Toll roads as a short-term fix for easing traffic congestion in places like the DC area. It is an interesting idea and might indeed provide a bit of relief.
Still, I tire of the continual spread of user fees for ordinary government services. Roads are one of the few things that even purists–including Adam Smith himself–believe should be provided by the state. Access to the basic infrastructure of society should not be segregated based on ability to pay.
