Rolling hoverboards are the new craze in the tech industry. They are self-balancing boards with wheels that you tilt forward to move and lean back to stop. They run for around $300 and are quickly becoming popular in the consumer market. Since they are motorized, they are not technically legal to be on the sidewalks. They cannot be ridden on streets either. They are only allowed to be ridden on private property, but many people are taking to public sidewalks around the world to ride them. Police are cracking down on the laws with them being able to be ridden on sidewalks and issuing tickets.
