CMV: Devices incapable of hovering should not be permitted to call themselves hoverboards.

A hoverboard is a well-known science fiction trope: a skateboard-sized device that can float above solid surfaces and is used for personal transportation and recreation.  

Today there exist some modified Segway bases that call themselves hoverboards despite the fact that they are entirely incapable of hovering.  If anything, they are less capable of spending time aloft than a standard skateboard.  However, their name causes confusion among potential purchasers and may mislead us into obtaining one despite the lack of the advertised capability.  Worse yet, if they become popular and retain this name, they may poison the original term and make great science fiction works like Back to the Future less accessible to future generations.

For these reasons, the devices should not be allowed to advertise themselves as Hoverboards.  Self-balancing boards or Headless Segways would be more reasonable.  

I understand that Patmont Motor Werks has registered a trademark on the term hoverboard for two wheeled scooters; this is not the source of my objection.  Also, their trademark should be sharply limited to ensure that actual hoverboard manufacturers can call their products hoverboards without legal difficulty.

"Fruit Loops" are not actually looped fruit.

A "Smart Car" is not an autonomous car.

A "3-D" movie is 2-dimensional.

The "Miracle Mop" is not truly miraculous.

There are many products where the name is not literally accurate, but is often effective in conveying to the public what the item is.

No one is going to be deceived by the name "hoverboard" once they actually see one.  There is no intent to mislead the public into buying one, only to discover that it doesn't really fly.

What it *does* do is tap into the desire to be Marty McFly.  Despite what we were told by the movie, we still don't have hoverboards.  This device does come as close as anything to letting you feel like Marty did in the movie.  Why not use that title?
