Golf Carts on Brattleboro Roads?

I’ve driven a golf cart in a community like this and it seemed like a great pollution-free way to get around.  Are golf carts allowed on the streets of Brattleboro?  Should they be?  I was struck by this quote in the article:

“Peachtree City, Ga., has roughly 13,000 households and some 11,000 registered golf carts.”
