Almost hit two tourists Saturday taking the scooters on a 50 mph highway at dusk. Wearing dark clothes. Dude had on a fedora and suspenders. Saw them just in time to serve.
I think they are great for getting around cities. In Nashville, they are usually operated by drunk tourists who use them to get from one entertainment district to the next. Just watch out because by Friday or Saturday afternoon, they are SWI (scootering while intoxicated).
