When you're a police officer out on patrol, you have no idea what's headed your way. It could be a nice, quiet day full of misdemeanor arrests and speeding tickets, or some nutcase could pull out a gun and shoot you during a routine traffic stop. It's a scary business.
The folks at Ford have come up with a clever way to boost officer safety in their new Taurus and Explorer-based Police Interceptor vehicles, and it uses existing technology. Called "Surveillance Mode" (which, I would argue, is probably not the best name in light of recent revelations), it uses the Ford's backup camera, cross-traffic alert and reverse park assist to keep officers aware of what's going on when they're parked.
