As a driver, I do my best to slow down a bit at any intersection, but particularly ones like this. Unfortunately, that tends to frustrate anyone driving behind me, sometimes to the point that they’ll try to overtake me (illegally) before the intersection.
In my mind, better traffic engineering is the best solution, but that seems unlikely, at least in the US. I’d imagine that the article’s suggested changes would cost more to build, even for new construction. To compound the issue, I get the feeling that most drivers would prefer it if cyclists weren’t allowed to ride on public roads.
