The problem is, it looks like they're trying to sell it as a car, when it's really just another glorified golfcarts.
It's funny that you mentioned Florida, since that's where I am at the moment. I'm only quoting parts of the laws, so this doesn't become a huge message. You can follow the links to read the rest of the statute and other relevant statutes if you want.
Golf carts can only drive on roads in certain communities and only in certain circumstances.
See Florida Statute 316.212
316.212 Operation of golf carts on certain roadways.â"The operation of a golf cart upon the public roads or streets of this state is prohibited except as provided herein:
The "Local Motors" vehicles would appear to be classified in Florida as LSV (Low Speed Vehicles). They're covered by Florida Statute 316.2122
316.2122 Operation of a low-speed vehicle or mini truck on certain roadways.â"The operation of a low-speed vehicle as defined in s. 320.01 or a mini truck as defined in s. 320.01 on any road is authorized with the following restrictions:
(1)âfA low-speed vehicle or mini truck may be operated only on streets where the posted speed limit is 35 miles per hour or less. This does not prohibit a low-speed vehicle or mini truck from crossing a road or street at an intersection where the road or street has a posted speed limit of more than 35 miles per hour.

The UTV is classified here as an ATV (All Terrain Vehicle), and covered by Florida Statute 316.2074.
316.2074(5) Except as provided in this section, an all-terrain vehicle may not be operated upon the public roads, streets, or highways of this state, except as otherwise permitted by the managing state or federal agency.
That's not to say people don't drive them on the road. I've seen them do it. They're breaking the law, and if the police are so inclined, they will be more than happy to give you a stack of tickets.
I've seen both golfcarts and various designs of ATVs used in a lot of places. A agree, they are popular for both industry and off-road applications. But with them implying it's a car it's a problem.
Honestly, it wouldn't be safe to drive any real distance in most metro areas in Florida, if it is accepted for road use as a LSV.
For example, I can't think of any routes that you could safely use to get from downtown Tampa to downtown St. Petersburg. You can't cross any of the bridges in that car, because they don't go fast enough. It would be virtually impossible to even find a route where you wouldn't be under the speed limit and significantly under the average speed.
Even downtown St. Petersburg to downtown Clearwater would be risky at best.
