hmmm I have an unexpected trued theory about hover cars ..... instead of making use of so much complex and intricate things why don't people try to use magnetic force ? simply put it you can use magnetic force to let two magnets stick together why can't they use the same method used to keep them apart earth has a magnetic force if you can use magnets to repulse that magnetic force you got yourself something that's hovering above the ground
(sorry guys I'm just not able to come up with too much at the moment between this storm keeping tired and my blood pressure being low or maybe it's my sugar no idea but I'm allllllllways tired but couple that with insomnia and I'm in zombie mode)
