There is no room for both your car and eleventy-thousand gallons of water.
That is all.
NO... ok, wait, there is one more thing. It's been raining all over New Jersey for two solid days, some towns are under about four feet of water, and the roads are impassable everywhere. So, when confronted with a long line of cars waiting patiently, one can safely reason that the drivers are NOT out for fun, admiring the weather. Therefore it's a bad idea to drive down the wrong side of the double-yellow lines to pass them all. At the next traffic light, there's another quarter-mile line of cars who are now uncomfortably staring at YOU, Mr. Too-Good-to-Wait-in-Traffic. Get a clue.
