sure, there are some parts of the US that get too cold and snowy, but there's plenty of the country that doesn't (like my own neck of the woods, southern california).

i was more pointing out that 2 relatively inexpensive changes (use scooters, convert parking to bike lanes) could dramatically change the balance of cars vs. public transport in those places (not everywhere). it doesn't have to require a wholesale change of our built environment to get benefits now (even for those dependent on cars).
