Speedometer Error

I know the topic has been talked about at great length here. And, I know there have been several solutions offered to find out your true speed versus what a Boxster speedometer will tell you. Don't forget about the HVAC diagnostics. Anyway, yesterday I saw a Sheriff's Deputy taking a snooze beside a local baseball diamond, so I decided to see if he believed in the "Protect and Serve" logo on the side of his cruiser. I asked him to clock me coming down a straight stretch of road. After a little grumbling he agreed. I held the Box (986) dead on 60 mph. When I circled back he said, "Looks accurate to me, I had you at 55 the whole time."
Just as I thought.
