I feel it's time to step way back and re-think our entire transportation system.
Mono rail trains or public transport is nice, but most people don't bother because they still have to get to the depot. If we use the technology we have, we could run a single track everywhere there is now pavement, right to every garage. Wow you say, but how much do we spend now to pave and repave?
What sold me is the endless and amazing list of benefits to this: No more drunk drivers because a computer could be programed to drive the car!(big one), An end to our dependence on foreign oil!(nother big 'un). Much less need for continental air flights! (These monorails could get to California almost before you made it to the airport and got through security)(oh, yeah and decrease terrorist threat by hijacking.) Decrease or eliminate exhaust emitions! (Oh 'nother big 'un). No need for individual car insurance, cause nobody is driving. You could sleep, read, drink or whatever on the ride there. You could send your pod to be maintained, send it to pick up your kids (with onboard camera), send it to get groceries or pizza from the automated store, or send it off to be parked until needed. They could be "parked" on all levels of a high-rise building!
I could see main tracks dedicated to un-interupted long range flow elevated and capable of high speeds. Friction could be reduced to nothing with air cusions or reverse magnets.
Imagine the economic surge when middle class familys didn't have to pay for gas, tires and insurance.
I am not a scientist, but I do think outside the "box" and I know the technology exists, but it's the benefits that keep this idea etched on my brain.
