> but never more at the expense of those that came before This is the standard anti-bike, pro-car argument in most American cities. That cars are already here, and adding bike infrastructure takes away from space for cars. The fact is, when you progressively accommodate more forms of transit, it's ALWAYS at the expense of those that came before. And that's ok. Pareto optimization is a lousy way to find a global optimum, in any system.
