> How exactly would this particular trade-off increase total deaths? Do you think this is happening in Oslo? What if I am having a heart attack and the ambulance is on the way? If it gets there within 5 minutes, I can be saved, if not I die. Oh well, no going over 20 mph, I'm dead. I would hope Oslo has a carve out for emergency response, but I don't see one in the article. Much, much, more abstractly, as the article points out, suburbs are much denser in American than in Olso. "If I could work on my lifesaving cancer cure 8hr/day I would cure it in 10 years, but at 7hr/day I only cure it in 12 years. I can only spend so much time at work and commuting. Oh well, no going over 20mph, it takes me years longer." Lots of productivity losses (some of which are undoubtedly going to result in loss of life) if a(not atypical) American 20 mile commute now takes an hour instead of 20 minutes. It would take restructuring of roadways on a massive scale in America to have this policy not result in staggering productivity/time losses. The article admits this ("it's going to require both institutional and far-reaching cultural changes", "It will take decades"). Without massive changes, adopting this policy would, as the article states, "incite riots in no time." I'd welcome taking steps towards transit restructuring. However, there seems to be little political will for even basic incremental steps. That's why zero deaths seems impossible - getting even basic, functioning, public transit is hard in America.
