I hear this a lot, but it’s not an excuse for never starting. Amsterdam started taking their non-car infrastructure seriously in the 1970s and now it’s seen as an example for the rest of the world.
“A society grows great when old men plant trees in whose shade they know they shall never sit.”
Asking to see a realistic roadmap and timeline is being a realist, not a defeatist. If Amsterdam started in the 1970s, that’s fifty years ago. Maybe we can make progress by the 2060s-2070s? Or we can just wait for China to manufacture all the EVs the world needs. Which is more likely to occur first?
Consider the US has $40T in debt and no will to raise taxes at this time, and therefore no will to spend on public infrastructure projects. Where will the capital come from?
How and when will we start? How many elections need to occur to appropriate funding? How much of the US electorate has to turn over for the right people to be elected to appropriate funding? Until shovels are in the ground, it’s vaporware and dreams.
