Commuted to work daily for over a dozen years here in Tucson.
Buzzed a few times, most likely unintentional/distracted drivers. Some perhaps fixated on my flashing brigh rear light thinking I was a barricade?!
Never got hit commuting to work in the dark, but did get hit in broad daylight about half dozen times with varous results.
However, each time the offending driver was ticket by police.
Am now 80 years young and still ride 100+ miles a week, on the road.
A vehicle coming within 1 foot is NOT close; 3 inches is getting close.
Be aware of your surroundings; follow the rules of the road. I don't count the 'close' ones!
Have pedaled 300,000+miles (right amount of zeroes) since early 1970s and am not about to quit now!
Pedal on!
