I remember back when:

• It was common for motorists to flash their lights to warn oncoming motorists of police ticketing drivers.
• During long-distance trips on the interstates, motorists would take turns being the lead car in the left lane (i.e., risk being the one ticketed).
• Tractor-trailer truck drivers almost always flashed their lights to let you know when you could safely re-enter their lane if you passed them, since they need more room than cars do to stop.

Does that make me old?
