I like this app mainly because I do tend to speed when I'm not paying careful attention. You get to choose from a list of voices (such as Spongebob, George W. Bush, and Yogi Bear to name a few, and of course a normal voice too) that will warn you when there is enforcement points, live police, red light cameras, speed cameras, check points, combo cameras, and mobile cameras. The only thing I would warn people about is that it eats your battery life crazy, so when you are not using the app, you have to select Quit from the menu. For some reason, it will not show up on the Advanced Task Killer.
