For the record, I love my bike and don't own a car. However, the local cycling "activists" in my community are from the same mold as the YIMBY, neoliberal urbanist types. Overwhelmingly white, PMC and childless, who view bicycling and bike infrastructures as the harbinger for livable cites.
When you're a coder or social media marketing douche sitting on an ergonomic chair for 8 hours, cycling for five minutes to and from your loft is an ideal arrangement. However, cycling is a lot less attractive to a blue collar worker who has to travel to a exurb for their grueling 9 hour retail or Amazon warehouse shift standing on their feet. They would much rather nap on the bus after a shift than push pedals for 5 miles.
There is significant research that bike lanes are a trojan horse for gentrification and neoliberal housing development.
In my mid-size city, the twittersphere about local city politics is disproportionately geared towards cycling. It's become a cool kids club for PMCs to get involved in municipal politics, while ignoring much more desperate issues like homelessness and police brutality.
your whole rant here is seriously misguided and uninformed.
cycling infra is not a concern exclusive to white, upper class, childless people. in many cities, the vast majority of people who bike are working class and poc, and they are also the people put most in danger of vehicle violence and police harassment when there is insufficient infra. because guess what -- cars are expensive to own and maintain and require licensing, insurance, and other forms of surveilled and financialised interactions that bicycling doesn't!
on top of this, your little vignette of a tired warehouse worker not wanting to bike is a super strange and paternalistic composite based on nothing. that aside, the entire existence of the exurbs and the expensive housing crisis in city cores is based on decades of autocentric planning and subsidies (which were bolstered by the exact same weird idpol arguments you're parroting here!) guess whose neighborhoods got torn down to build car infra? which populations suffer disproportionate health issues due to highway exhaust?
it seems your basing your entire critique on what you see happening on twitter, which is not real life whatsoever. there's no such thing as a cool kids club, either get involved or don't, but don't make your petty grievances and surface level understanding get in the way
