the problem is not cyclists, it is cyclists having to work with a bad design that is based on the lowest common denominator of skill. The bigger problem is drivers.
This type of design which "seems" safe because it has car's as a barrier creates a lot of issues with visibility and lanes being blocked by non cycling users.
protected infrastructure (of which I am not a fan) requires, separate signals to avoid these issues
There is no one size fits all in infrastructure, but what has been pretty successful multiple situations in my area has been road diets....ie changing a 4 lane (2 lanes each way) to 2 lanes, with a center turning lane, and 2 large bike lanes. Motorists scream, but in general this has resulted in better bikeablity and even walkability where it was done, but again that may not fly in downtown chicago
