Antigravity blocks for RC car tracks

This is going to be hard to explain so buckle up…

Have you ever played Mario Kart 8 or Trackmania Lagoon and noticed how some tracks allow you to ride on walls or ceiling? What if we had a canvas block that allowed this for Vehicles, Ball Race Orbs and RC Cars? That could open up a lot of things…

Oh, players could also walk on it too. You could make some cool condos with that.
