More than 20 years, peak car ridership occurred in the 1970s which was close to 80% of urban transportation done by car. That number is now down to 19% of all urban transportation done by car.
Amsterdam also had backing from the public to transition to bike and public transportation.
Absolutely we should invest in public transportation! And you are right that cities have decided to create public transportation, and then did! But it took a decade plus to plan, build and implant the new system. That’s also ignoring the millions and billions of dollars needed.
I have an engineering degree, so I know my share of physics. I can smell bullshit about mechanics and engineering no doubt. I can gather the evidence, I know where to find it, how to judge the quality and conduct experiments to test my theories. But my knowledge is limited to my domain.
My knowledge of biology or climate science is limited. I’m not an expert nor do I try to be an expert. I don’t have the time or the skill set together better evidence comb through the different theories and the mountains of data to come to my own conclusions. I must trust the scientists of their fields because they trust me with my knowledge. It’s impossible to be an expert in multiple domains in today’s world.
It’s unreasonable to ask to draw conclusions of highly complex systems that most people will need, at minimum, a domain specific university degree to understand.
