If you want to move on from racing in video games to the real world, there is a lot of expense involved. First you need to purchase a capable car, and then buy some safety equipment, and then pay for track days or join some sort of racing league. Even the amazingly accessible autocross has an appreciable cost — and a lot of work. You could do all that, or you could follow this tutorial and build a first-person view RC car.
There are two major sides to this project: the controller, and the RC car. The controller is an enclosed seat with a steering wheel. The driver sits in the seat and wears Fat Shark VR goggles that receive a video feed from a camera mounted on the RC car. The steering wheel moves a custom gear linkage that in turn spins the RC controller steering knob, and a trigger is used to control the throttle.
The result is racing experience that feels at least somewhat similar to driving a real car. Unlike a video game, you get to drive a car that is subject to the real forces of physics. You won’t, of course, get to feel the g-forces that you would if you were actually racing a real car. But, this is an affordable way to race in the physical world, and would be a lot of fun if you can get a few friends together to compete in a parking lot somewhere.
