I can't even believe it's necessary to point these things out, but:
Motorcycles are dangerous, but are available. So are personal airplanes. So are hang-gliders. So are bunji-jumping gear. All are available - just not to kids. For those of us over 18, sky's the limit. We're free to smash our brains out, and the manufacturers would waste no time offering us new ways to do it, parents be damned.
Hovering 'snowboards' would be HUGE - imagine that you could 'board down any hill, anywhere, at any time of year? Not a chance that market would be passed up.
Plus, if the technology existed to make the things work, there'd be a million other uses for them - hovering wheelchairs, hovering hospital gurneys, hovering cargo dollies, etc.
But the physics DON'T work - how exactly do you steer a hovering board by leaning? It has no friction with the ground, and would squirt right out from under you. Skateboards steer that way because of the way the wheel mounts are designed. Surfboards steer that way because of friction against the water. To achieve the same effect with air would require a MUCH larger surface area - or a velocity so high, you'd be swept right off the board.
Zemeckis is having fun with you, and if you had an English teacher who believed they were real, she's a twit.
