well, if we tried, maybe 10-15 years off before full implimentation, the trains are already working perfect, as are other applications using the same technology. it pretty much comes down to redoing our current road system to be magnent compatable and building a whole new vehical. so you might be right about 50 years, but only because we want to be nice to these oil companies and not put them out of business... the technology is there, its 1000x cleaner. "cars" would not need alot of power if any, just to run the onboard controls, so you could program in your destination. only the roads would have to be electricomagnetically operated. i picture it like the current nav systems where you put in your destination only instead of it telling you where to turn it takes over and takes you there, and since the whole road system is operated via magnents you can easily control vehical locations and speeds, making accidents near impossible on a funcitional system.
