@FlyingSquid lots: probably thousands of blowouts and power lines, about a couple dozen derailed cars.
How many miles of paved highways in the US? How many people transported via rail, & over what distances over the past week? How many miles of power lines are up? How many miles repaired?
Development doesn't mean perfection and/or things never needing repair; it's more about having the infrastructure that needs to be repaired.
You ignored GDP. What do you define as a "developed" nation?
I was curious about the number of passengers carried by rail, so I looked at the wikipedia page. The US is 12th with 533 million passengers in 2019, which I find surprisingly low when compared to the population/size of this country. In France, same year, there was 1880 million passengers.
I don't think the rail infrastructure is well developed in the US, probably to the benefit of car infrastructure.
A third or so of the country wants America to "lead" and not "follow". So they resist change they percieve as being pushed on them from outside, no matter how logical or beneficial.
