I've lived several years in Germany and The Netherlands. So, I have seen it. I am not an expert on it but I've seen it. There are big differences between our systems and theirs. Many things that work there, would be difficult to implement here in the USA and vice versa. Look at their transportation system. Their train system is a great way to travel. Of course, it comes with a price, those railway right of ways are often unsightly and criss cross everywhere. People travel by bicycle as much as cars, can you imagine that in the USA?
In European countries they have far less vehicles. The price of buying a vehicle is much more. In addition, there's the cost of fuel, insurance, inspections, and taxes on the vehicles. Yes, we have that here in the USA but it take more of their disposable income, there. All of our vehicle traffic takes a hard toll on our roads and bridges. Places I visited in NL had cobblestone roads that were laid long before I was alive. I would drive on a four lane from Steenwijk to Soesterberg. The road was beautiful, flat and rarely crowded.
The faster we build roads, the more vehicles are traveling on them. The more damage is done to the roads. Our infrastructure is in the shape it is in from use not lack of attention. I can't remember the last time I drove from my home in Monroe, GA to Orlando, FL and did not encounter construction zones. We are constantly working on these roads. Always building new bridges, paving sections, adding lanes. How many airports do we have in the United States? How many miles of roads? That's all infrastructure that we've built and use without even thinking about it.
