A line of marchers? Or a mob of violent communists wielding weapons and attacking the cars on the road? Were the roads blocked off for the peaceful weapon wielding line of marchers?
Why was the driver on that one way street? Had he been parked there? Did his GPS send him down the road?
For what it’s worth, I’ve seen bizarre behavior from GPS based driver guides. In Kansas City, Google Maps sent me more than once on an unasked for visit to a side neighborhood. A careless finger dab on a screen can change a route to a side track and still the destination seems the same.
