Amsterdam has put extensive resources into converting its streets for safe biking.
This has made biking a completely relaxed and pleasant mode of travel with the result that 30% of all travel in Holland is on bicycles.
In contrast Portland's bikepaths are almost exclusively narrow and streetbound and give the feeling of vulnerability and discomfort if not danger.
On Portland's unfinished streets bikes ride on the edge of the pavement with no buffer of safety.
In contrast in suburban Portland a simple asphalt path separate from the roadway makes biking and walking safe and comfortable.
The same separate pathways need to be added to every rural highway. This one in Oregon is very rare.
