You clearly haven't spent much time on YouTube, TikTok, Twitter, FaceBook, or really anywhere there is a huge community. Americans fucking HATE cyclists.
> The great majority don't care about it
My own dad will take any opportunity to actively bitch about perceived annoyances perpetrated by cyclists and opine about how useless bike lanes are expensive and not actually productive because people only use them for exercise. Why don't you try actually bringing up cyclists and bike lanes somewhere, especially in the south, and then you tell me what people think.
Drivers mostly hate on other drivers, but they make time to hate other road users as well.
> Americans fucking HATE cyclists.
I haven't met those Americans, somehow. Maybe it's just more social media nonsense - people joining the mob fun and far overestimating the loud voices?
Did you ask them? Lots of things I don't like don't come up until it's relevant.
