The cost keeps dropping and the specs keep getting better and better, but they seem pretty dangerous, mainly because you have to share the road with cars. Still, for the price of an ultra cheap beater car, less than $2000, you can get an electric vehicle with 50+ miles of range and 30+ mph speeds, that you can fold and carry with one arm (if you're kinda strong).

I've got a basic one and its great. My only gripe is that I don't feel comfortable locking it up on a public street due to theft, so if I want to scoot to a store, I have to bring the scooter in with me. Would be great to see this mode of travel widely adopted, with some decent infrastructure like rentable lockers and more bike paths that aren't just the shoulder of a street full of cars.
