well.. i thought about it like have computer system that will guide you.. and the speed will be changed by bosters.. there are 2 kinds.. the one that uses wheels the pushes it forward.. and then the magnetic kind.. that pushes forward..

the compuer will know if one goes faster then the ones infront and break.. also.. boosters could be set here

in german train development i heard they are building trains flying on magnets.. that push it forward.. works aliittle that same.. but it doesnt fly..

if this will be done.. a new city might be the first step..
someone rich might build his own city. and people who come visit will have to park outside..

teleports.. yeah.. that would be great.. if the superstring theory actually works.. we could.. not very likely IMO..
