We have VERY few protected lanes, mostly there are "sharrows" aka faded pictures of bikes on the road that do absolutely zilch. I am routinely honked at and ignorant/rude people yell things out of their car windows at me, usually because I'm going too slow/am in their way on the very narrow (designed before cars) streets. Cars simply dominate due to the wealth and political power of all the car owners (many of whom have Florida plates to avoid local taxes). Do any of the politicians even ride bikes to their legislature or have any understanding of cyclists' issues?
An illustrative example of our inadequacy is going in between two fantastic/picturesque protected paths: the East Bay Path along Narragansett Bay to the Blackstone River Path. You have to pass through 5+ miles of the urban and narrow streets of Providence, Pawtucket, and Central Falls. It's honestly a nightmare, I'd rather bring my car to transport my bike from one path to the other than ride in between myself, breathing in exhaust from old clunkers and trucks, experiencing road rage and petty rudeness, and of course nearly getting hit on multiple occasions.
Let's get our act together and make a network of protected lanes across the North East corridor. With electric bikes coming to the fore, I'm hoping more and more cyclists will be able to cover longer and longer ranges, thus facilitating low-emissions, healthy inter-city transport.
