In a world with global warming where many cities stated goal is to reduce vehicle miles traveled, it doesn't make sense to ban a valid mode of transportation.
Just two days Dorothy Bruns in Park Slope ran through a red light, killed a four year old and a one year old. A pregnant woman is still in critical condition. She hasn't been arrested.
Maybe the NYPD should concentrate on felonies before worrying about violations.
And I say this having grown up my entire life without a car, biking everywhere. I'd take tickets for riding on the sidewalk, and I'll do it every single day I ride. Sharing a road with 2500lb vehicles that go 2-5x my speed is unsafe and all the talking and lane marking in the world will never undo that fact. Nevermind how utterly anti-social and rude you must be to bike in a lane 20mph under the speed limit.
I spend as much time as possible in the Netherlands since they seem to be about the only sane country when it comes to mixed-mode transportation and not trying to murder people while doing so.
Don't worry it's not uniquely American:

But is it asinine and destined to fail? I'm not sure.
I think that it IS possible to share the roads but only under low-traffic and low-speed conditions.
The worst offenders are cyclists on busy dual-carriageways during peak hour and it is horrendously dangerous, with two lanes of traffic forced to snake around a single cyclist.
On side streets however I don't think it's a big deal at all.
It isn't uniquely American. There's no need to make over the top claims. It undermines your points.
