A traffic tip for clueless drivers:
When your interstate on-ramp is metered, and the little sign beneath the light says "Two cars, this lane, per green," they mean that two cars get to go when the light turns green. Not, two cars can make it through when the light is green but if it turns red and you haven't made it you must stop cold in your tracks. Nor, if you're talking on the phone and hesitate and the light changes you just sit there while the person behind you has to throw his or her hands into the air in frustration at your stupidity. Two cars per green light when indicated. It's not rocket science. It's math, and even I can count to two.
