New Cadillacs to Warn Drifting Drivers

We've all done it. At some point you're driving and you get distracted, or you start to nod off, and your car starts to drift out of its lane. If you're in the market for a new Cadillac, your car may soon have your back. The Cadillac SRX, ATS, and XTS will all sport a new feature that will vibrate your seat whenever you start to veer off course, Detroit News reports.

A key selling point is that the feature won't embarrass you in front of your passenger. "It's quiet, it's private," says Cadillac's safety director. The seat will even vibrate on the left or right side, depending on which way you're swerving. They use sensors and cameras to figure out when to sound the alarm. The system may not be Cadillac-exclusive for long, either; GM often gives new features a test drive in its premium line before expanding to other models. (More Cadillac stories.)
