Life as an adult doesn't have to be boring as you can still enjoy it like you use to when you were younger. Of course, some people won't accept it, but you don't have to answer to them. As long as you are not doing anything wrong then you can do anything that you want. RC racing isn't just for kids anymore as most adults are using it to kill some time. RC toys aren't that affordable and that makes it an adult toy. Anyway, you can find some like minded individuals that share the same interest as you, so you won't need to hang out with friends that judges you.
Since, this is a race, it understood that you need to win it. you need to drive your vehicle as fast as you can till you reach the finish line. But, it won't be that easy, especially since there are lots of obstacles along the way. Also, you need to make sure that you are ahead of the pack and be able to get to the finish line first to advance to the next level. That won't be easy as the other players would be aiming for the same goal as you. You need to get ahead of the rest as early as possible to win the game.
