The online racing games you find these days are mostly browser games. This means that you would not download special files or programs to make them run. Just go to a reputable online racing games site and click on the one that you would like to play. After a few minutes the game would load on your browser. At that point, you are free to play it and finish it until you get your racing thirst quenched.
It is always fun to play races because it is mostly a fast-paced game. You will not have to spend hours on them, unless you really want to emerge as the big winner. In which case, you need to master the skills and the controls to play the happy wheels game. And in a real gaming world, that could take a couple of days. However, the fun and the excitement that you obtain from the game are going to be worth all those time spent on it.

These flash-based games are perfect if you have an immediate need for a dose of speed. While you can rarely flash-based games on your computer, a few clicks of the mouse are all you should make to make it going.
