A case of playing "chicken"???
I live in an affluent area, northern burbs of Chicago. And in recent years a huge increase in the number of sporting cyclists on the roads. Sometimes I think motorists get annoyed with our presence.
Last evening I went for a short spin. I have a 20 mile route that goes through less traveled roads and an MUP. One of the roads goes through a residential area. It's sort of the last undeveloped streets around. No curbs, and the road is less than 2 lanes wide. So if cars were to pass they really have to slow down to a crawl. A car and a bike passing each other, no problem.
I rarely encounter a car on this street. If I do they are courteous and slow down and pull over as far as they can. Until my encounter yesterday. I could see a car approaching, black Mercedes with blacked out windows. It was approaching fast. Me I was in bright red jersey, white helmet, very visible. I assumed they would slow and pull right. I was as far right as I could be and still be on pavement. They kept coming maintaining their position on the road. We passed each other, the drivers side view mirror maybe 6" from my handlebars, the car going 25mph?. It wasn't comfortable. And the car never changed its course, even though we were in eyesight of each other for some time.
Close encounter for sure.
