Fatalities of people walking steadily falling and then something tragic happened in 2010 to flip the curve. What?

So number of deaths halved between 1980 and 2010 so right things were being done. What changed besides cars getting significantly heavier and electric??

Can someone explain why we need HAWKS? What is the benefit over a stoplight that all drivers understand. Is their purpose to safe seconds for a person in a car? Truly curious. Put a camera on them if compliance is the problem and be done with it.

Engineers are leading the charge to shift 100 years of car centrism that permeated our country with a laser focus on safety. SS4A x 20. Tell your town to apply if they haven’t already. Tell your DOT to fix all the arterials they control. Support safe walk and bike networks.

@Boenau You guys think we live in a world that doesn’t yet exist. Safety is not like Bewitched. People without helmets on bikes and motorcycles will be in crashes tonight. Some will die. Go hang around an ER. Their chances of survival would be better with a helmet. It’s very simple.

Off topic. If housing simply kept pace with inflation your house would only be worth twice what it was in 1995 today. Maybe housing should not be an investment to make money from and has become big part of the housing problem young folks face today.

A national inventory of sidewalks needs to be completed. The places with closest to twice as many sidewalk miles as road miles will most often be the most walkable cities and towns. A separate program encouraging building of sidewalks will pay for itself in future health savings

I really don’t understand why there is not free WiFi in busy places such as metros, train stations, tourist areas etc.. It’s as if it’s by design NOT to provide it. The most frustrating thing about travel is a lack of good WiFi when you need it which is most of the time.

By the early ’30s, the war was over. Ever after, “the street would be monopolized by motor vehicles,” ….By the 1960s, cars had become so dominant that when civil engineers made the first computer models to study how traffic flowed, they didn’t even bother to include pedestrians
