Another “not a car”… but close… It has 4 wheels and a steering wheel. It drives kind of like a car. Basically, it is a revolutionary product called a “side by side” ATV, or UTV. Specifically, it is a Yamaha Rhino.
Originally, these things were glorified golf carts. Then they became more like utility carts. But, like most things with engines… somebody had to hot rod one and take it off-road. And then the racing started.
