Take a look at the paint next time you drive by. Is it marked with black streaks from tires crossing it? Would driving habits change if, say, some large rocks were lined along the paint stripe?

Without at least bollards the road isn't actually thinner, so people don't actually drive slower. And without at least bollards, I wouldn't let my kids ride in a bike lane— which means many other people won't feel safe either. It's unfortunate that politicians get away with this willful disregard.
