The folks making Vectrix Scooters show a certain amount of courage, displaying their wares in the land of Lambretta, Piaggio, etc. I would think that if the regenerative brake does its job, it could be a winner in urban riding. There is a lot of gas that gets used up, only to heat the brakes at the next stop light. That's true whether its your standard SUV or a Big 4 Rickeyracer.
If the quoted range is 60+ miles at a steady speed, it should go all day in congested traffic, I'd think. If I ever move out of the sticks (nearest town with 10,000 people is 80 miles away), I would think hard about an electric scooter.
Well, it wouldn't sound as good as my Ducati - but then nothing from the Big 4 or Milwaukee does either.
