Even in the Bay Area, the Lincoln Ave road diet in Willow Glen (San Jose) was severely divided, and I considered the Bay Area to be way more bike friendly than other regions in America.
Since Portland and Seattle are 180 miles apart, it's probably fair to argue that Minneapolis-StPaul combined is the best or second best current bike metro in the country. Similar in population size to Seattle, bit bigger than Portland.
Does anyone have a good up to date source for miles of protected bike lane per city, thats been updated since last year?
