It's like when the fuckcars crowd tells everyone they should just bike to work even though there's plenty of people that have deal with mobility issues, children, winter, not being in their 20s and etc. etc."
But those are reasons to be against car-centric design[1], and in favour of public transport - the disabled, children, the elderly, those with slowed reaction times, the poor - can't actually drive, or safely drive, or legally drive, or afford to own, cars. If cars are the only option for transport then life can only be good for the healthy mostly-able-bodied car driver[2].
> "One size doesn't fit all."
In all too many places, the only size available is 'car'; that you rally against bikes - and implicitly in defense of the status quo - while reminding people that "one size doesn't fit all" is dischordant. Can we have two, three, four sizes then? Walking, bussing, biking, tramming, driving?
> "is a thing someone else can't live without."
It's not an accident that you can't live without your car. Los Angeles had the largest electric tram network on the planet, and car companies used shell companies to buy them up and scrap them. Car companies spend a lot on advertising and propaganda to sell the idea of car ownership as a kind of American Freedom, and various zoning laws came to mandate car parks around businesses - pushing everything too far away to walk. It's not all conspiracy, but it's certainly not an inevitable "the way things must be". Arguing that 'fuckcars' people shouldn't want bikes, because some people can't live without cars, is reinforcing exactly the kinds of things they are angry about. That having to have a car to live, is an unquestioned default.
[1] not cars necessarily, but urban planning, laws, town and city layout, spending priorities, traffic priorities, where all the levers have been pushed fully over to cars.
[2] and being stuck in traffic on an ugly stroad which costs vast amounts of taxes to maintain and is dangerous to drivers and pedestrians, with car fumes, is not a particularly good life for those people either.
