So if you can't safely overtake a bicycle, you expect it to stop by the side of the road to let you pass after 20 seconds?
When cycling, under such circumstances, I usually stay between two parked cars until the traffic is better (that is usually after a switch of traffic light to red). But again I try to stay in reserved lanes, much safer.
Same goes for bicycles, they've got places to be. It's a means of transportation just like a car. If there is no bike lane, that's though luck for the cyclist (as it's a lot less comfortable) and for the motorists behind them, and a good reason for cyclists and motorists alike to argue for more bike lanes. Why should they alone bear the cost of shitty infrastructure (in time lost stopping by the side of the road every time a car is stuck behind them for +20s)?
