I guess I measure urban bike friendliness differently. Most indexes emphasize infrastructure, I emphasize conduct.
I live and ride NYC's northern suburbs, commuting at least 12 miles round trip daily, besides daily errands, and sport riding on weekends. My area has very few bicycle specific amenities, with the most common being simply designated bike routes marked with some signage but not much else.
OTOH local drivers are generally very aware and used to sharing roads with cyclists. I get passed with good separation, don't get yelled at except for the occasional "where's your helmet?", and overall am treated with courtesy and respect by a very vast majority of motorists, truck and bus drivers and cops.
Given the choice of having bike specific infrastructure along some routes or being respected as an equal road user everywhere, I'll take the latter any day.
