Starts as fun, but gets boring pretty soon because you just restart the same course everytime you run out of gas before the pitstops. However, that's not why I uninstalled it, it's because of the ads which are ridiculously often. Every 2 rounds you get an ad and then a long one every few more rounds. I just hate this kind of apps. Just give me less functionality for adfree and more extras for paid version, but don't stick your ads in my face every minute.
