The history reported in this article is very interesting. There are a lot of contemporary photographs of changing American cities. The quotations from experts provide perspective on the visuals: "'If a kid is hit in a street in 2014, I think our first reaction would be to ask, "What parent is so neglectful that they let their child play in the street?,"' says Norton.
"'In 1914, it was pretty much the opposite. It was more like, "What evil bastard would drive their speeding car where a kid might be playing?" That tells us how much our outlook on the public street has changed."
Indeed. Are we really thinking carefully about how to spread the risk around, when so much of our living space is dominated by cars?
AFTER EDIT: The video link shared by pugz[2] in a reply comment elsewhere in this thread is not to be missed. Car safety standards have improved enormously in my lifetime, but those protect the occupants of cars better than they protect pedestrians and bicyclists who are hit by cars.
