Having a good amount of reasonably well maintained dedicated bike lanes would have made rollerblading to work a lot easier!
I am seeing more and more e-bikes though, which, since you can keep up with traffic relatively well, allow you ride in the car lane under most circumstances. That's what I do, and if some dickhead really feels the need to pass me when I'm going >25mph, I'll give them a wave at the next light. And probably be shot in the chest one of these days.
People get creamed on bikes all the time in bike lanes. Pedestrians on the sidewalks and bike paths just don't pay attention to anything other than what is 3-4 feet from them, and are always forcing you to dodge if you have any kind of speed if you're just even jogging.
It's more a cultural problem than a city planning problem. Contrast how seriously bike lanes are treated in (say) Munich, which is very seriously.
