The usual scenario of following something a bit bigger than you that appears to be dawdling and then slows almost to a stop, many impatient drivers/riders look for an overtake muttering under their breath...is it a case of the driver looking for an address, having a seizure, kid running out in road etc etc. Everyone's in too much of a rush which is pretty evident with mateyboy on his motorbike who would no doubt have intercom so would have been able to tell his students that he was temporarily baulked and that he'd catch them up
its also up to the driver in front to show his or her intentions, people aren't mind readers
lets say, your driving an HGV truck pulling a heavy load, your coming off the roundabout accelerating and going up through the gears and also looking in the mirrors to see if any traffic is along side the trailer as you exit the roundabout, when suddenly a car stops in front of you in the middle of the exit
you might find it very hard to stop that truck in a hurry,
