On the other hand "Hoverboards" became famous for bursting into flames so vigorously that people thought they were exploding, so maybe there is a deep connection. Then again "Hoverboards" were actually available on the market as advertised for quite some time, which is probably going to differentiate them from yet another Musk gimmick.
Add it to the list, boys! "Inflatable Rescue Submersible", FSD, Bulletproof windows, Mars any day now, Hyperloop... am I missing anything?
