      It would probably be worthwhile to design cities to encourage this: to design cities to be fast to get around by bicycle. How do you do that? We know how to encourage cycling in an existing city. But if you were designing a new city to be optimal to cycle in, what would you do?https://twitter.com/asymco/status/1118530522144235521 …

      Twice as many Copenhageners cite speed as the reason to cycle vs. cost. (53% vs. 27%). And that’s still with few eBikes in use.

      As few roads as possible. That may well mean: no roads.

      Surely you need to get ambulances in and out?

      I wonder about moving to an all-helicopter approach for that and other essential functions (police, fire, etc). Trucks and things like food supply would still be significant issues.

          IMO college campuses already provide a great model: have wide concrete / paved paths that can be used by important vehicles (ambulances, box trucks, etc.) but where it's made clear that they're not intended for use by personal vehicles.

          Weather conditions (likely unmodifiable) and cost (modifiable, but scale questionable) are prohibitive right now. Do you anticipate significant enough of a shift to make this feasible? Or are you answering in the ideal sense

          Amsterdam seems intentionally optimized for bikes, with skinny roads for cars, and fat bike lanes. The primacy of the bike lanes is obvious, and everyone bikes everywhere there. The city is also arranged radially.

          Firefighting airships could be useful in low rise areas.

          imo just as cruise ships have dedicated highways for delivering baggage, maybe underground rail network for food delivery
