I will say, however, that cost is one of the primary issues which is rarely addressed. In the USA the dollar is king and it shows in all aspects of our lives.
Compared to automobiles, Bicycles are too cheap for their own good. America would have good cycling infrastructure If bicycles cost $20k to purchase, $5k per year to fuel, $500 to register, $1,500 year to insure and if the bicycling lobby spent hundreds of millions of dollars bribing politicians yearly.
Drivers (why isn’t driver a dirty word?), at least in the USA, have a clear sense of superiority and entitlement which drives (pun intended) their sociopathic behavior. “I spent $50,000 on my Tesla and thousands more on licensing and maintenance! That money gives me the right to get back to my bedroom community in San Mateo as quickly as possible, fuck you and your 2-wheels, i’ll run you over with zero legal consequences” is a common attitude.
The USA will never get dutch-quality cycling infrastructure until bicycle riders spend driver-level money.
