The big Coast Guard base near me uses a bunch of these. Even though they don't have Gov license plates, they use one public street that runs alongside the base perimeter. Some, Mitsubishi brand IIRC, seem to have a top speed of 35 mph and are pretty close kin to motorized golf carts with a truck body.
15-ish years ago, I used to keep an Isuzu Pup as a spare vehicle. You couldn't kill that thing.
