Note please, I did say that if there were no cars parked there, that it would be possible. Obviously with cars parked there it is not possible.
And in the video, based on which you accuse him of holding up traffic there are cars parked there. So you concede that it's not possible for him to move in there in this instance.
We could be discussing that all day and night, what is legal and safe are the most important considerations, followed up by consideration for other road users.
The cyclist is being both legal and safe in that video. The motorist is being unsafe in needlessly blowing his horn at the cyclist, and is showing no consideration for the cyclist by attempting to intimidate him.
There are 2 parties at fault there, two wrongs do not make a right.
Except there aren't in this case. There's one wrong, an impatient motorist with a sense of entitlement losing their temper over what is at most a ten second delay.
