Didn't miss that at all. Just didn't see the point. At all.
Maybe it's not about you- directly.
First, if you want to know why I might want one, move to the Pacific NorthWet for a year and get back to me about making a quick run to the grocery store. I can gear up and ride, or take the car. The car wins most of those, especially if the weather forecast is "liquid sunshine".
Second, environment aside, having two wheels (or three) makes it a motorcycle, which gets it around a LOT of federal crap about what a car (with four or more wheels) has to have and be able to do- and if used as designed as an urban commuter, conditions it will never see, which keeps every car bigger, heavier, and more complex than it has to be. (Seen many cars less than 3000 pounds lately? Me either.)
Having a roof and a steering wheel means no riding gear or helmet necessary- though in most states the driver will still have to have an endorsement- a good thing, most car drivers don't know how to manage traffic the way motorcycles do. That gets more drivers used to and looking for small vehicles- like motorcycles. Go ahead and tell me that's a bad thing. (It's not the main problem with motorcycle crashes, but still.)
Is it for you? Maybe not. It's for people looking for an economical (concidentally fun) way to get from the burbs to work and back. Right now, a lot of people are getting on scooters that shouldn't be. As energy prices go up, I see things like this increasingly being the right choice for them.
