I'm a SF resident who was visiting NYC last week, and saw those protected bike lanes for the first time (I lived in NJ a decade ago). Frankly, drivers' attitudes towards bicyclists will be slow to change, and thus the only reasonable course forward seems to be this kind of infrastructure improvement. As infrastructure improves, more people will consider bicycles as a reasonable transportation alternative, and hopefully increased numbers of cyclists may help driver attitudes change as well.
