Reducing the amount of car trips, is how bike lanes improve safety. Even if nothing else convinces you.

If efficiency isn't relevant for you then I don't know what to tell you. Transporting more people, getting them where they need to go at low cost to the person and to society is something most people think is a good thing.

There are not tradeoff, research is pretty clear, improving in biking improves the situation for drivers as well. And the claim that 'people are not willing' is simply because, people are misinformed.

To claim Poland is to hot for biking is freaking ridiculous, its equally ridiculous to claim its to cold. Biking is much more common in places Finland and in the Nordics. And in some places in Switzerland. Poland is mostly flat. Netherlands are also flat and rainy. In places where Poland has improve their bike infrastructure, they have seen adoption. Poland in literally every way is like other nations, so get out of here with your Polish exceptionalism.

Not all post-communist nations are de-urbanizing. Superannuation is a direct result of policy not some 'cultural will'. Infrastructure and policy is deterministic to a far, far greater degree them 'cultural memory'.

Demographics are why you can't have bike lanes? Now you are just flat out ridiculous.

Poland growing economically and many people are moving to Poland, including many poles who left. And in regards to drivers, that an equally crazy claim. Driving a vehicle is not some intellectual job that only a brilliant physicists can do. And the claim that the city can't afford it is equally wrong, much, much poorer society then Poland have managed to run a bus system. Are you fully pricing the roads and the parking? If not then that's how you can get some money, and improve the system.
