On Memorial Day I walked outside and did a double take - my quiet street, tucked away many turns from any main road, was backed up with cars from end to end. I'd never seen that before in 5 years here. Turned out it was Waze sending beachgoers (I'm still 30 minutes from the beach) on a side route to the nearest on ramp for the highway that heads to the coast. Within an hour there was a police car here diverting drivers and the town put up cones to stop it.
What's frustrating is this "shortcut" was completely ineffective. It simply moved the traffic jam from the main roads to our tiny neighborhood.
