Ever since Back to the Future II, people have dreamed of riding a hoverboard.

It's easy to see why: the idea of skimming over the ground with nothing underneath is pure science fiction — though many believed that it would always be fiction and nothing more. Attempts have been made, but nothing's ever come of it, plain and simple.

Then, Lexus released a short teaser of a real, working hoverboard. It was straight out of a sci-fi movie: with seemingly no extra support, the board was floating just above the ground. As more and more details were revealed, it quickly became apparent that this wasn't Marty McFly's board ... but the fact that it even existed was more than enough to keep most people excited.

Now, Lexus has revealed a second teaser, featuring an updated model of their hoverboard — and, if there were any doubters left, this latest video should definitely change their minds.

Again, it's a short trailer — don't expect to see much in the way of details. That being said, while the first trailer was vague, this second teaser does a good job of showing that Lexus' board is really hovering on its own. That last shot of the board and its rider walking alongside one another should be more than enough to convince anyone that the tech is real.

Then again, it doesn't seem like Lexus is ready to show anyone actually riding the thing: it's clear that the board is floating, but no one outside of the company has ever seen someone actually use the board. Yes, it's still in testing, and it's amazing that the board can float on its own ... but it doesn't mean much if you can't actually ride the thing.

Considering it's been less than a month since the board was first revealed, it's possible that Lexus is getting ready to show its hoverboard off in a more detailed fashion. Until then, all we have to go on are the teasers themselves — hopefully, it won't be long before we know more about Lexus' latest tech.
