Shocking News in the World of Traffic!

I saw someone on Route 1 start to do the infamous "drive in reverse on the shoulder of a busy highway because I missed my exit and I am too lazy to proceed to the nearest U-turn" maneuver and then actually stop mid-move -- I am assuming they had a sudden epiphany and realized how stupid and unnecessarily dangerous this particular vehicular move is  -- and the car merged back onto the highway, do do a legal U-turn somewhere down the road, I assume.
