Not coming to a complete STOP is a biggie. On Space Shuttle missions, when they return to land in Florida, as the Shuttle rolls to a stop, the Mission Commander onboard says, “Wheels Stop”, into his microphone. THAT is the end of the mission. At a STOP sign, you have not stopped until your wheels STOP.
At a STOP sign, you have not stopped until your wheels STOP.
At least until people learned this simple rule.
When I was about 12, my mother got a warning for failing to come to a complete stop. The cop told her that all 4 wheels have to stop rolling, which I thought was extremely funny.
