Reflecting a recurring theme at Signifying Nothing, the administration’s announcement of its plans to sorta-kinda invest in high speed rail brings out the predictable reactions: Cato says it sucks, the central planning enthusiasts love it, and Prof. Karlson and John Stilgoe remind us that relatively inexpensive, incremental improvements are probably a better use of taxpayer money than flashy bullet trains over the distances Americans are likely to travel by rail.

My view, as always, is that all of these promised lines are of little value if they are not connected to the transportation system that most Americans already use: airports and their associated amenities like safe long-term parking and the rental car counter.
