Ok so I have seen this a few times now. Driving down the road at night and glance over at the car next to me and BAM!!! there it is in blue and white the drivers speed clear as day. So I ask myself why on earth would you want everyone including that cop car driving next to you to see exactly what speed you are going, no need to even pace you. Just drive up next to car look at their speed and see ok hes going to fast. What a good thought. If your not going to dim your instrument panel then your just asking to be pulled over.
