Electromagnetism for instance,Imagine the underside of a car,was a whole flat twenty inch thick magnet,.And imagine it to be a whole magnet,,And then if you can‘‘Try and picture putting two magnets where the bumpers would be and those magnets/bumpers were to be switched on n off like electromagnetism do you think it could lift the car by using the opposite magnetic force?Like imagine an ice rink only instead of being all ice ,,all magnet and a skate board only with no wheels but the opposite force on the under side of the hover board type thing ,,Could it fly.Im sorry as although I know what I mean in exact detail but putting it down in writing is quite difficulty.Like I say ,,,Serious answers only.And thank you for taking the time to read this .
Levitation by magnets is like balancing on a ten foot pole. It's inherently unstable. Remember the other end of the magnet is as attracted to the other magnet as the first end is repulsed so the magnets will be trying to flip around. In 1842, they proved mathematically that it would be impossible to come up with a stable static repulsive configuration of magnets as you've described. Even mag lev trains only levitate by fractions of an inch so magnetic levitation will hardly be the back to the future DeLorean. There is a type of magnetism called Diamagnetism that would have the properties needed for stable levitation but diamagnetic forces are so weak that you can barely levitate a fly. unless you really crank up the juice. That Frog that's levitated is levitated because organic bodies are weakly diamagnetic hence they put the Frog in a 15 Tesla magnetic field to levitate. That's an incredibly strong magnetic field, one that could wipe out all the hard drives for blocks around it. I doubt that you would want to bring your laptop with you if you did have a magnetic levitating car. Don't forget that magnetism has an effect on the brain as well. You could really be scrambling your thoughts, never mind the laptop if the magnetic field was strong enough for diamagnetic levitation. Current efforts are to try and use permanent magnets for the lift but diamagnetism for stability. The maglev trains in use today use very quick computers and sensors to adjust the magnetic field as needed. Most commercial maglev trains use attractive forces rather than repulsive as the attractive forces are more stable. Note that superconductors are the strongest diamagnetic material that is possible.
It's not a stupid question I always think of the same idea. But there are problems. The best option is superconductors. There's such a thing as the meissner effect where a magnet can levitate over a superconducter. But the problem is that superconductors need to be super cooled for them to work. But as materials are developed we might find a room temperature superconductor which might mean that your idea will become a reality. I think you should really google and research about superconductors. It's fascinating.

They build roller coaster rides for amusement parks using magnetic levitation technology. I believe also that the Japanese use mag-lev technology The main problem with your idea is that these ride above a charged rail. Just lining a vehicle with magnets is not enough.
