With all the talk of futuristic 3 wheel commuter "Motorcycle" prototypes out lately such as Elio and Sondors, here is one that is actually for sale. It is a fully enclosed electric trike that can go on the highway. In California you can use hov lanes since it is somehow considered a motorcycle.
This arcticle says Electra Meccanica has an agreement with Zongshen to make 75,000 of these things by 2020. I would like an Elio but who knows if they will ever be produced.
