Aye, I Think one might be able to outwalk the cars as well. Doesn't take much strenght to bike twice as fast as this either. I don't think I'd even consider a car.
What's the percentage of car ownership for the population over there? I think N-O had 30% car free people, which made the evacuation for drivers faster.
Are we seeing the results of a majorly car-owner population trying to evacuate?
