Allstate Patents Physiological Data Collection

TigerPlish writes: Allstate has been granted patent no. US 20140080100 A1 for a "driving-behavior database that it said might be useful for health insurers, lenders, credit-rating agencies, marketers and potential employers." The program is just in the patent stage for now, but the company says: "the invention has the potential to evaluate drivers' physiological data, including heart rate, blood pressure and electrocardiogram signals, which could be recorded from steering wheel sensors." Imagine a world where you are denied employment or credit based on the information obtained from your car and sold by your insurer. What could possibly go wrong?
