Forget the Lexus hoverboard. The WalkCar is one strangely alluring Roomba-like skateboard you can pack away in your bag when not in use. Made of sleek aluminium, it’s set to launch on Kickstarter in the next few months in two versions: indoor and outdoor. And it will weigh just 2 to 3 kg. That’s certainly lighter than the estimated price tag of 100,000 Japanese Yen (about US$802).
