When I took Drivers Ed in high school in the 1990s, my teacher told our class that whenever you're about to pass a bicyclist on the road, you should always give them a friendly and courteous "Hello Honk" just to let them know you're there.
It's a lesson that's always stuck with me.
As a result, whenever I pass someone on a bicycle, I – like most OKC motorists – rev the engine, honk the horn and give a "big friendly" wave. It doesn't matter if they're pedaling around Lake Hefner, coasting through the rural'esque backroads of Eastern Oklahoma County, or simply taking up the entire right lane during rush hour on N. May Ave., it's something I do every time. You know, because it's nice!
