Would never work in St. Louis where, sadly, the government's idea of a bike lane is painting a picture of a bike on the pavement. Seriously, outside of a few roads in the city, most the so-called bike paths run down roads that are just busy enough to be considered somewhat heavy traffic, but just slow enough to have stop signs instead of traffic lights. The result is a need to stop at a stop sign every .25 miles. It's almost as if the people in the government who plan these things don't ride bikes.
