Golf carts, in reality, are not carts, as carts "cannot move under its own power." A golf cart is pragmatically powered by an electric motor or a gas engine. One neat feature of a gas powered golf cart that helps differ it from a regular car is that when one takes their foot off of the gas pedal, the engine turns off. "This feature helps save gas, cuts down on emissions, and helps keep the course quiet, too.” Golf carts also have been primed with electric battery motors that can be charged or even energized by solar panels upon the roofs of the cart (source). A golf cart is an LSV, otherwise known as a Low-Speed Vehicle, ranging from about 20 mph to 25 mph. Compared to other LSV's, there is little difference, as they mostly operate quite similarly. That being said, is it possible to modify golf carts to accelerate faster or pick up higher velocity? It is seemingly possible and simple to do so, however dangerous and unlawful. Insurance companies may deny paying for damages and individuals may risk traffic citation (source).
The golf cart was created sometime in the year 1932. However, it wasn't very widely accepted. Not until the 1950s, when the company Marketeer developed the first electric cart designed specifically for golf. At this time, many courses did not allow the carts, some required to have a physician's note to own and operate one, and these golf carts were still fresh and expensive. The industry grew immensely in the 1970s when companies realized they could manufacture golf carts for basic means of transportation elsewhere (source). The penultimate example in central Florida proving this would be The Villages, as more often than not, residents use golf carts to traverse the area, even as far as having mass cart parking spots and driving lanes.
