Not long ago I was reading about the problem of gridlock on the freeways of Southern California –the traffic jams which cripple the city, stranding millions and laying waste to time, energy, and the environment. Gridlock is as serious and as impenetrable a problem as any we face, a dilemma without cure, without solution, like everything else in the world, it seems.

Some smart folks concocted a computer simulation of gridlock to determine how many cars should be taken off the road to turn a completely jammed and stilled highway into a free-flowing one. How many cars must be removed from that commute until a twenty-mile drive takes twenty-five minutes instead of two hours? The results were startling.

Four cars needed to be removed from that virtually stuck highway to free up that simulated commute… four cars out of each one hundred. Four cars per one hundred cars, four autos out of every one hundred autos, forty cars from each thousand, four hundred out of ten thousand. Four cars out of one hundred are not that many. Two cars out of every fifty — one driver out of twenty-five drivers.
