Great analogy. I'm visiting a particularly car-centric city atm, and from the car driver's perspective, "nobody uses the bike lanes, I never see them, so why build them, it constrains traffic". Well ya, there's so much car traffic because it's car-first, and nobody wants to be around tons of cars, not even people in cars. It's like arguing that you never see cyclists on the freeway, therefore nobody likes biking and we should discourage it.
