It's a good idea in theory, but having ridden this setup in Golden Gate Park[0], I'm constantly worried about getting doored and ride as far away from the cars as possible. I'd argue one's chances of getting doored are higher than an auto rear-ending a biker, so it would take up a lot more space to implement correctly. Also, for passenger in a car, can you imagine (carefully) opening a door, hoping not to door a biker, only to try to cross a stream of bikes to reach the sidewalk? It's a bad scenario for all parties.
