As a driver, it can become problematic when cyclists don't stay single file along the white line. You don't want to slam on your brakes because that could cause an accident behind you and you don't want to swerve into oncoming traffic and kill yourself, but it would also really ruin your day if you hit a human being. I have several friends that are bikers and would agree that it would ruin their day if they were hit or if they were the cause of an accident.
As a runner, I have had several close calls myself. I always run facing oncoming traffic and when I see a vehicle, I get over to the left as much as possible. Unfortunately, when drivers pass another car, it puts them in the lane that I am running in and oddly enough, I was not born with eyes in the back of my head. It is frightening when you have a car that comes up behind you and is only arms length away traveling at 60 mph.
Please take caution when training as an athlete and also as a driver. I did not want to create an accident by taking a picture to show an example of bad cyclist etiquette. Instead, I will share with all of you a bumper sticker that sums it all up, Share the Road.
p.s. On this Fourth of July holiday weekend, please do not drink and drive/bike/run.
