The only problem is that the choices they give... wide road with bike lane or wide road without bike lane, both encourage motorists to drive faster.
What we really want are narrower slower roads that are easily shared by all... very much like the European model that is so often touted as existing because the cities are so old. (disclaimer... yes, I know all of Europe is not the same, and cycling differs from country to country, but for expedience I am citing "Europe.")
The fact is the best solution for sharing the roads are narrow slow roads... if that is not possible for some reason (IE "the distances are too great, we need arterial roads... bla bla bla") then the next best solution are well designed bike paths along well designed high speed roads with appropriate signals for crossing and turning.
Since the latter won't be paid for... we end up with what we have... the mismash of bad roads, bad bike lanes and wide multilane arterial roads that drivers use as "freeways" when they think they can get away with it... with the end result that cycling modal share in the US is very low.
Of course in a dream world, I would prefer independent networks for motorists and cyclists as they have in places like Oulu Finland. But that is just a dream.
