Thanks, and you're right about the vehicle spectrum. 

It would be fun to see what kind of improvements Tesla or some other innovative company could make to golf carts (or similarly small vehicles) if they got government approval to make them road-legal.

I bet we'd see a proliferation of new form factors like how batteries not only enabled e-bikes but also all sorts of e-scooters, one-wheels, e-skateboards, and even different style bikes.

Cars vs. Bikes - Both Sides Are Wrong

Wonderful headline

I don't even think it's specifically about golf carts, but you're definitely onto something. There's a whole continuum of potential vehicles between bikes and cars, but they can't legally be used in the US.
