Technically, you can use a backup camera in a race car. However, it doesn’t necessarily mean you should. In-car camera systems have been in select NASCAR race cars since 1983, offering the public a view of the track from inside the car. Sadly, the images made spectators dizzy. And while tremendous improvements in video quality have been made since then, the high-speed nature of racing also means you have plenty of road vibrations to think about. These vibrations can still lead to choppy and dizzying video feed from the rear camera. As race car drivers need to focus on the racetrack ahead of them, they only glance at their rearview mirrors in a split second. Even if you have the most sophisticated rearview camera, you wouldn’t really use it very often.
