If high-speed police chases were half as exciting as this Need for Speed: Hot Pursuit trailer makes them out to be, everyone would be doing them.
Of course everyone would also need to own a souped-up Porsche. In my experience that is a lot harder to achieve than pissing off the police. I'd expect it is even easier to piss off the police if one owns a tricked-out sports car, but the chances of me getting to test that theory out any time soon are slim.
It's probably just best to keep it all in-game when Need for Speed: Hot Pursuit hits stores this November.
