[Star Wars CU] How does "speeder"-type levitation even work?

It seems to be a constant thing whether the conveyance is off or on. Usually, they seem to maintain basically a constant height over whatever surface they are on, but sometimes people can go over other people on speeders. It doesn't seem to take power to operate but crashed speeders crash to the ground. What is it? How does it work?

Gravity is a *solved* technology in Star Wars. 

Even the two gun turrets in the *Falcon* have their own gravity, separate from the rest of the ship. Even TIE Fighters, mass produced and so cheap they don't even get shields, have the bottom of the cockpit be *down*. 

Now, that doesn't mean these systems can't be damaged or fail. But as long as it is intact, it seems like the only reason a hovering craft would need to touch the ground is for long-term storage.
