I live in a rural area of Indiana where it is very hilly (Yes there are hills in Indiana! The whole southwestern part of the state is very hilly.). There is a group of bicyclists that like to ride the hilly curvy roads in my area, which is understandable because it's very scenic. What I don't understand is how they manage to not get hit by cars all the time. These roads are narrow and winding. The crests of the hills are quite sharp. Visibility is very bad. I'm a slow driver, so I've never come close to hitting anyone, but the average driver would have very little time if any to react if they came over the crest of a steep hill or around a sharp curve and there was someone on a bike right in front of them.
I grew up in a rural part of Michigan and can remember riding a bike when I was a kid. Someone came up with the idea of "bike flags" and my parents got us some. This was back in the 70's. Whatever happened to these? As safety minded as everyone is these days, I can't believe they're not mandatory. I'm thinking about dusting off my old Schwinn touring bike and doing some riding again, but there's no way I would ride a bike in my area without a bike flag! Why doesn't anyone use these anymore? Is it "not cool" or something?
