Four Democratic U.S. Senators have written letters to Apple, Google, & Research-In-Motion and asked the companies to remove any apps that are designed to alert drivers of police checkpoints and in some cases appear to cater to intoxicated drivers:
Senators Frank R. Lautenberg (D-NJ), Harry Reid (D-NV), Charles E. Schumer (D-NY), and Tom Udall (D-NM) called the apps "harmful to public safety" in a March 22 letter to the three mobile industry leaders.
One such app is Buzzed, a 99-cent utility in Apple's App Store that alerts users to DUI checkpoints within a 100-mile radius of their current location.
