> Heavy car traffic is a stable system that's actively unfriendly to pedestrian and bicycle uses. You need to slowly claw away space for bicycles and increase ridership; and then work to densify and intermix commercial and residential for things to work well. > > It takes decades, and the initial steps make things worse even if the new equilibrium is better. Your point about the stable equilibrium is correct, but there's no reason it has to take decades. If you look at pictures of cities like Amsterdam, Paris, and Vienna from not long ago, you can see how much more pedestrian-friendly they were made, and much of those changes actually happened more or less overnight. The actual changes are pretty easy to implement. Red tape slows it down, but that's a feature of our own invention, not an inherent limitation.
