Additionally, the system creates a sort of targeting reticule that appears over nearby cars, letting you know when you're perhaps driving a little too close. (That, of course, is when you have to switch from missiles to guns.) The head unit recently became available in Japan, and while there's no word on a release date or price in the US, hopefully it won't be long off.
