Inaccurate speedometer - 986 Forum - The Community for Porsche Boxster & Cayman Owners

In the past, I clocked my car at +3mph versus GPS and road signs. It is annoying but has probably saved me from many tickets. However, I would have an issue with +5mph assuming what you are testing the speedo against is accurate.

Today, I clocked my speedo at +5mph from a road sign. I am wondering if the police set it to show you a lower speed than your actually speed so they can ticket you.

I'd really like to shrug that off as paranoia, but now you've got me thinking. With all the red light cams and photo radar, traffic tickets have become a major revenue source. It's not that much of a stretch for them to pull a stunt like that.
