It's very rare for cyclists to be holding up traffic for anything more than a few seconds and usually only in specific scenarios (e.g. going up a hill on a narrow road). It's far more common for motorised vehicle congestion to be the thing adding delays to people's journeys and bizarrely, there's a common mindset amongst drivers to always want to overtake cyclists even when just a cursory glance ahead shows that they can only make a tiny bit of progress until they join the queue at the next junction. It's referred to as Must Get In Front (MGIF) and annoys me when cycling as often an unsafe overtake will be performed by a driver and then I'll go filtering past them a few seconds later - why overtake when it makes no difference to your journey time?
