There are few things more jarring than when you're doing 80 on the freeway and spot a well-concealed police cruiser. You immediately begin to sweat, get your story strait, perform a mental check-list of license and registration, then watch the rearview mirror like a hawk to see if he pulls out. If you get the ticket, your day is ruined. If the cop was looking down, eating a donut, or just wanted a more brazen offender, flowers smell sweeter and your step is a little lighter.
