Actually, it's gotten worse than that. For a long time, the design
manuals for bike facilities warned of dangers regarding weird
infrastructure. For example, I own several editions of the AASHTO design
manual for bike facilities. It listed about a dozen detriments of
segregated bike paths at the edge of roadways. These were problems that
were obvious to the engineers compiling the manual - things like
motorists not noticing cyclists off to the side and colliding when
cutting across their path. Or ignorant bicyclists turning left from a
right edge facility. Or wrong-way cyclists zooming unexpectedly into
intersections. The manual didn't absolutely forbid such designs, but it
cautioned heavily against them.
That didn't sit well with the "paint & path" crowd, the advocates who
think there's no such thing as a bad bike facility. So first, they
formed their own organization, NACTO, and put out their own quasi
manual. Rather than a design manual, it was an exhaustive collection of
every weird idea conceived anywhere. It was intended as inspiration.
There was almost no actual design information, such as dimensions
necessary for safe use by bicyclists.
The next stage, still pretty new, was taking over AASHTO. "Paint & path"
folks got themselves onto AASHTO's committees, and modified the manual
to permit all their weird ideas. The manuals now encourage "do anything
you think is a good idea."
So bi-directional on-road bike lanes that have increased car-bike
crashes by factors of ten or more? Check! Great idea!
