Can you possibly make a hover car by using magnetic force? What I mean is can you put car with a magnetic bottom over a magnetic panel and make them repel the car above the panel to make it float. To stop the car at a light a panel would come up as the light turns red to repel the car from moving. To stop the car in a drive way you would press a button that slowly magetizes the cars bottom to make it stay and to start the car you do it the same way but in reverse. Last but not least to turn your car connects to a magnetic track that turns the car for you. I hope you can under stand what I'm saying because I really thing this could work!

It is possible, and there are magnetic monorail trains, old japanise/russian invention. But magnetic cars and roads are too expencive.

I thought that may be a problem
