Coming back from the Giants-Dodgers game (Kershaw is pretty damn good)... Anyway, I'm blowing down 280 and 85 on SF peninsula and south bay and was not expecting LIDAR. I was probably going 88 on initial hit, used brakes to get down to 75 before killing. There's an acceleration and deceleration lag on the camera speed display - as to be expected with GPS. Anyway, I was way into 'ticket zone' for CHP. This is why I bought these devices.
