True. But if you could get 90% of non-work stuff a cycle ride away (groceries, childcare, post office etc) that’s already a big one. London, another massive sprawl, opened what’s called “cycling superhighways”. These are on disused railway tracks, covered with high quality tarmac. Wide, straight, lit, off-road, bike-only trails taking you around the city (into the centre in particular). I wouldn’t call London cycle-friendly but these really make long commutes feasible. A friend of mine, no exercise freak, happily cycles 40 mins each way on one of those.
