Why do you think driving buggies to work would be bad? Where my in-laws live down in AZ they allow street legal UTVs. Not sure about ATVs (I'd assume so) or buggies, but side by sides are everywhere. Not only is it not a big problem, it seems like the more people driving them the more accepted it becomes. Granted, I don't live there and my opinion comes from hearing the in-laws talk about possibly getting one as well as me being a fan of side-by-sides. It's also a small town across a river from a small NV town, and nothing but desert and rocks surrounding it - not like the urban sprawl we have here.
I'd love to pick up a UTV, use it for my around town nice weather vehicle, then take it to the desert or mountains on weekends.
