Seems like a good idea in Taiwan. I have spent some time there, mainly in Chupei and Hsinchu. These areas are about an hour south of Taipei. Traffic there is pretty much a free for all. The cars basically sit still while the scooters and bikes filter around them. No shoulder or crosswalks there. It is AMAZING that there are not more accidents. Looks like Taipei is a little better for bikes. Don't know if the idea would work here in the states.
Funny, many of the engineers I have talked to over there want to get a car as soon as they can. It's the final thing that signals "I have finally made it" and am a success. This is even though traffic is horrible and no where to park. Many of their jobs going from Taiwan to mainland China now. Guess we all have the same problems.
