allow denser packing of stopped bicycles

Currently bicycle lane takes as much pace as car/bus lane what is understandable (for simplicity reasons, though you can remove one car lane and have enough space for two bicycle lanes).

But it results in very weird results in case of bicycle traffic jams, with extremely low density of stopped bicycles - what increases risk of deadlock.

Would be feasible to allow smaller gaps or make bicycles smaller? I guess that two lanes of bicycles in one lane would be obnoxious to implement.
