In California it seems a lot of cities decided to try and add bike infrastructure but the design process yielded many compromises, since that infrastructure comes at the expense of car (and parking) infrastructure. As a result we got really bad bike lanes, but gave up few parking spots. The design process declared victory via compromise- best of both worlds. In reality, the bike lanes are worthless and cyclists like myself just use the primary vehicle lanes, since not dying is more important than protecting the convenience and respecting the supremacy of other road users. Drivers honk and yell and deliberately endanger you, but that was true before too.

The article talks about using design and engineering out of the problem. I do not believe that is what was done in the cities you cite, even if that was their headline intention.
