For many people, this would make taxis cheaper than public transit and you would no longer have the critical mass necessary to support public trans.Did any of you guys see the documentary Urbanized? I believe it's on NFLX instant. There was a really interesting segment about the debate to build a subway / lite-rail in Bogota, Colombia, IIRC. Anyway, they basically concluded that buses were more efficient if appropriately planned out. Pretty interesting.
