Once, when we were stopped in a traffic jam on the New Jersey Turnpike, I saw a line of cars peeling off of the left lane, passing through a space in the median and entering into the opposing traffic on the other side, just to avoid whatever was causing the slow-down — until a state trooper pulled up in the vicinity and spoiled the fun. Unassisted he was able to stop two vehicles and issue tickets. Naturally, no one attempted the maneuver after this. Forty people must have made that illegal turnaround, but the last two got stopped.
I think episodes like this justify my inability or unwillingness to make a decision. Just ride it out, no matter how bad the accident ahead my be, because the alternative could be met with sirens and flashing lights.
Or… Just make the decision sooner.
