Ford's MyKey system has been engendering teen resentment since the release of the 2010 Focus, allowing parents to limit max speeds and cap radio volume, but parental control doesn't stop there -- the 2011 MyKey can selectively block radio stations. Starting next year, parents will have the option to block 16 Sirius radio channels from the car's dial, among them Howard Stern, Playboy, and Hip-Hop Nation. Optional radio censorship isn't the only new feature for MyKey, which allows owners to program a key to fit their specific level of paranoia -- the new version allows parents to set top speeds between 65 and 80mph, instead of the previous fixed cap of 80mph. Other controls carrying over from the original system include a chime that sounds at 10mph intervals, starting at 45mph, and an advanced notice when fuel levels are low. The new features will come standard issue on the 2011 Ford Taurus and Ford Explorer, and will eventually reach across both the Ford and Lincoln brands.
