Bike riding is still fun and safe dedpite the lack of government assistance.
The safe part is relative, depending on where you are and what your skill level, experience level and tolerance levels are. I ride in a lot of different environments from busy urban to single lane mountain roads with no traffic, and I have to adjust, of course, depending. My mirror allows me to feel much safer in the traffic areas.
As far as the bike accommodations in the US compared to European countries, we are way behind many of them. Our culture is built around cars and the ability to go anywhere at any time in a car. And our tax rates, especially on the rich, are very low compared to the social democracies of Western Europe and compared to our own 50-60 years ago. There just is not the money to spend on so many things. When I was a kid, camping was free, as were national parks, state parks, etc. Now we can't even afford decent veteran care and we have bridges collapsing on us. Think there's much money left over for bike amenities? We have financial structural problems that preclude such frivolities. Meanwhile, the richest of us have second and third homes, yachts, etc. The European democracies with high tax rates have the highest standard of living in the world, better health care, etc, and , yes, better accommodations for getting around without cars.
Don't expect our situation to improve a lot until we get a more equitable tax structure and we have the funds available like we did in the halcyon days of the mid-twentieth century when deficits were manageable and benefits and amenities generous.
