So short of getting something that support the weight of a person, this thread has got me thinking about using the seat bolts to support just a board by itself. I'm thinking I could get just a thinner, flat piece of metal. Bolt it to the 4 seat bolts on the driver's side. Have it extend past the sill straight out. And then just attach the hover board to the top of it. It would look like the board is just floating beside the car. And this wouldn't take any fabrication that is above my skill level.

Otherwise I am having a hard time picturing what Alexakos is describing with hinges. Care to paint me a picture?
