(although you might be correct about green paint, thats fake infrastructure and paint won't protect people from getting hit by cars)
Also, painting more lines on a road is usually more of a half-hearted municipal response to requests for bicycle infrastructure; the changes that are established to improve ridership are physically separated bicycle lanes, the network effect of more cyclists, and holding drivers responsible when their behaviors kill or maim more vulnerable road users.
The amount of people who call me insane for cycling on London roads is no joke.
LA may have been the poster child of poor planning in the 80's, but i'd suggest cities like phoenix, houston and atlanta have surpassed it in that regard.
