This, to me, signals the general attitude people have towards bicyclists in the US. The average person either doesn't care or, for some misguided reason or another, actively hates bicyclists. I've been yelled at by drivers for no apparent reason so many times I've lost count. I've had so many friends hit by cars. My partner was struck by a car last fall and broke her leg in two places. She's still recovering and frequently has to lie down for hours because her leg is so sore. Just the other day a friend of mine was struck and had to get stitches in her face.
I think the problem here is a mixture of infrastructure and attitude. The infrastructure side of things is usually what we talk about, which is obviously an important part of the discussion, but I don't think the problem with peoples' overall attitude towards bicycling gets enough attention. There are so many people out there who legitimately wish to harm bicyclists. Don't take my word for it, in 2016 a driver purposely murdered 5 bicyclists (in an area close to where I live, no less) with his vehicle and was sentenced in 2018[1]. Although most are likely accidents, there are other examples of drivers purposefully striking bicyclists with their vehicles if you look.
It's really sad, I think it's a symptom of something a lot more sinister happening to the hearts and minds of people in this country, and it's why I no longer ride my bike in the city anymore.
