@Roy Kamisato:  That's not true.  Especially about the part on driverless cars.  That particular solution wasn't even discussed 4 years ago because the technology was only in a concept stage back then.  It was also never brought up by any of the major candidates.  Nobody from PRP or the current Mayor's campaign or even the Cayetano campaign brought any of these alternatives that could have been implemented instead of building the rail system.  If you can prove otherwise, show me the statements from the campaigns that stated these alternatives to the masses.  You seem to have this bias that rail is the only solution to our problems and so we should build it regardless of the cost.  My point in the three posts above is we didn't have to spend all this money, but Mufi, Caldwell, and others decided to go with this wasteful option that benefits their union friends and private companies now involved in building the rail.
