Hey guys, just about 5 min ago I was driving home from the local super market to pick up some eggs. Well my light turned red, and just in front of it is the "Your Speed is" sign right before you get into the construction area. Well I stop and by the way I am the ONLY car around. The sign is blank, but my radar is screaming K band. I take off and the sign jumps to say I am doing 22 mph, I am only at 15. I think nothing of it until next it says 39 mph (the speed limit is 30) I am only doing 25, then next it read my real speed at 27 mph. Now this really confused me, if this sign can say I am doing 39 when I'm not what's to say the police radar gun wont say that too? Does anyone know why it would do this? Could it be because I was accelerating or is there something more?
