It is a public street that was designed to service the neighborhood and the traffic traveling to the neighborhood. It is not a highway.

It is easy to share a pie between two people. It is very hard to share a pie between 400 people. In the US roads ARE NOT designed as a shared space between people and cars. If you play in the road you could very well die due to one person on a phone when they shouldn't be.

Stay alive, keep off the road.

That's the problem. Kids cannot safely play in the street in many "safe" neighborhoods in the US. They should be able to, but they can't. Americans practically worship cars. The roads are treated like sacred land. Safety and happiness are set aside for the sake of motoring.

Why should they be able to? Mass + velocity = splat. You can't deny the physics.

The Americans worshiping cars boat sailed like 70 years ago, it is too late to do anything significant about that in a short period of time without spending trillions. Unless you think replacing most of our infrastructure and moving massive numbers of people is a good idea.

And the roads are treated like scared land. They are the arteries and veins of our economy and life.
