He could have slowed down and pulled in out of the way of the car, it is technically possible.
The cyclist as has been shown throughout this thread and indeed due to his own Twitter footage, that he has a very arrogant nature and seems to think he is invincible whilst cycling. His sole purpose seems to be to aggravate motorists, for the sole purpose of gathering footage for his Twitter feed.
No sir, both are wrong.
The cyclist is delaying the motorist regardless, he could have attempted to cycle on the left side, had he done this then the motorist would have noticed that the cyclist was at least attempting to move into the side of the road and out of his way.
I am sure the motorist would have thought, fair dues but the road is too narrow here.
But the Chicken man would then have no footage.
