To those not familiar with this term, it refers to unmarked police cars. Last night I sat stuck in traffic and some $%#$ in a brand new Nissan Maxima, fancy wheels, tinted windows (very sharp car) went cruising past everyone on the shoulder. I muttered under my breath about how there is never a cop around when you want one, only to find out later, this was a ghost car! Usually I can spot a ghost car a mile away- big, American, black wheels, antennas, only a ghost car to the visually impaired. But to use an expensive import sedan is unusual here. Any other strange ghost cars you've seen?
