A large car, but with the proper planning and rights, i.e., bus lanes, a large car that moves.  I was in a cab riding into Seoul and the buses in the bus lane went flying by us.  Rail is an idiots dream.  I lived outside of Chicago (McHenry) for 10 years. Took the train when I needed.  Drove in when I needed.  Train would get you to the central station in Chicago, you either walked the 20 blocks to where you wanted to get to or you got a cab.  This island Oahu is not nearly accommodating to rail.  Don't kid yourself.  Fasi, as good as he may have been, did not have to deal with the details.  And that's where the devil is.
