Using ions on roads to make cars (with the same ionic charge under them) float?

Hello, Please do not think of me as an idiot at my crazy ideas but I am just trying to think of a creative science fair project. I think that if we could place ions in roads and under cars while they both have the same charge, will the car float? If even a little? Since N+N and P+P repel, wont the road's... show more Hello,

please take it seriously and tell if you think it makes sense or not.
Thanks in advance.
