I'm (honestly just a little) surprised there's no mention of Scoobi, who just launched in Pittsburgh. [0] Other than an opening weekend issue involving a few friends "terrorizing" them [1] they seem to be successful. I've seen several folks riding on them, many parked (legally, thanks to an agreement with the city), and none the worse for wear.

Personally, I'm going to try one, on a weekend, before I brave the jagoffs of rush hour.
