It wouldn't be cheap, and it would require a lot of fuel to run intercity (I wonder why they don't use linear induction motors rather than jet engines, given that you have to have the guide rails anyway...it would be cheaper, simpler, less prone to failure, lower maintenance, not require on-board fuel, and be potentially much "greener"), and, of course, a complete redesign and rebuild of our whole intercity road system, but it could be done, technically. What will prevent it happening is the first glance at the problems...other than those implied above. Things like terrorists interfering with things physically on in software and causing massive crashes that shut down intercity travel for weeks to months while the system is re-built at the crash site (for sure) and perhaps everywhere to close the security hole (very likely...see NASA and shuttle crashes). Maintenance issues...at the moment a small road defect, such as a pothole or a dead animal, is a minor problem and unlikely to cause serious problems. Cars running at 300mph under computer control and constant adjustments based on feedback from sensors in the vehicle as well as the road system will be different. A deer jumps in front of a vehicle and the vehicle is history...along with whatever parts of the road system get in the way of the fragments....or exploding fuel if they stick with the jet engine propulsions system. Vehicle maintenance is another issue...how many techs at the local dealership are qualified to work on something as complex as a jet aircraft? How many of those would you trust with your life in one? What is technologically possible isn't always possible when you start looking at cost, risk factors, failure modes, politics, and other problems. Those are the main reasons we don't have flying cars flitting between domed cities today. If you can work out solutions to all the non-technical problems, you could end up very, very rich... -- Mike B. -- Pie are not square. Pie are round. Cornbread are square.
