I was driving to work early on a beautiful summery Monday morning, mentally already in the office getting ready for a busy day. As I approached one familiar intersection, there was a different speed limit sign – not the typical “Speed Limit 20” post planted in the ground, but one that said “Speed Limit 20” and, below it, an announcement of my speed – 27 – in flashing lights. It went even further, flashing a message saying “Lower Your Speed”, which I promptly did.
