The writing has been on the wall for quite some time, but now it is on paper too. 2015 ended badly for the self-balancing, two-wheeled board, with many catching fire and harming their riders. Some manufacturers and a few retailers have started pulling what would be considered deathtraps on wheels, and now there is official government weight to those actions. In a letter to manufacturers, importers, and retailers, the US Consumer Product Safety Commission described these hoverboards as posing an unreasonable risk to fire. That is, unless they meet safety standards. Problem is, none of them currently do.
