When driving on the freeway in heavy traffic and something happens ahead of your car, the tail lights of cars far up the freeway light up, warning you of problems down the road. It can look like the lights on an airplane landing strip, each red light sequencing its turn to glow immediately after the next one in front, so that fifty lights covering a mile can rush toward your car in just seconds. It can be an immediate warning system, if one chooses to see it. Flashing brake lights that far in advance of a problem, can save your life, unless you are so preoccupied by “other stuff” you don’t heed the warning. Unless you are too busy to see the warning signs; then a big crash may be in your near future.
