Cushman is STILL in business.
A number of the small utility vehicles used by Disney World in Orlando, FL, are four-wheeled Cushmans. They have a full complement of lights, and ample seating for operator, but are considered not road-worthy because they lack a number of mandated safety features.
John Deere builds the Gator utility vehicle, which if ever ruled roadworthy, would be the modern equivalent of the post-WWII Jeeps. There are a number of other manufacturers of similar utility vehicles, most of them of Asiatic origin.
