Rapid Transit, monorail whatever, is a social accessory. In biological terms the tail on the dog.
The experience however, is invariably the monster tail with tiny dog attached. The servants very quickly become the masters, by affecting prices and expenses, without regard for the overall health of the original plan.
Fortunately, no government (yet) has found a way to both keep people from using their own cars, and simultaneously forcing them to pay exorbitant amounts to use the "public transit" system, which invariably becomes another insane combination bureaucracy and welfare system.
The whole nightmare is punctuated by the new oligarchy being able to hold hostage millions of citizens by going on strike and paralyzing all transportation, of course.
Rapid transit is normally accompanied by total neglect of the normal highway system.
Since gas prices have gotten so high, our genius politicians here in Ohio are now TALKING (what they do best)about a light rail system going from Cincinnati to Cleveland. And guess how much they are saying it will cost to ride this thing from Cincinnati to Cleveland? Approximately $200.00 round-trip! Even with gas prices at $3.00 a gallon, you could drive it for less!
