No, in fact, my assertions are wholly based on in-person interactions with motorists, in conversation and on the roads. I’ve literally been spit upon and road-raged, and many voters and taxi drivers have expressed their sheer hatred and opposition to public transit.

My assertions have nothing to do with “online circles” except here where I am breaking the bad news to y’all.

If you haven't spent time in "online circles" then why is your understanding of vulnerable road users and non-car options limited to only bikes, light rail, and Critical Mass? What about rail trails projects? Does your area follow any NACTO guidelines? How does your DOT/DPW see things?

I don't deny the general idea that motorists in the US tend to have a crab mentality on the road where they want and expect everyone in the road to only be other drivers. I've also been sneered at in various ways in every non car form of transit I've been in.
