End of the road for hoverboards in colleges

Many universities ban 'potentially dangerous' self-balancing gadgets

One of the holiday's hottest presents is now considered contraband at many US colleges.

At least 20 universities have banned or restricted hoverboards on their campuses in recent weeks, saying the two-wheeled, motorized scooters are unsafe. Beyond the risk of falls and collisions, colleges are citing warnings from federal authorities that some of the self-balancing gadgets have caught on fire.
