The cyclist clearly wasn’t going to hit the pedestrian, but it was very much tool-ish behaviour (both against the rules, and it’s not fun to have people whizz close by you, even on a bike).
That said, it is absolutely 100% routine for motor vehicles to do this where I live (admittedly not the UK – a northern European country – but I imagine it’s not that rare in the UK either, given that a taxi does exactly the same thing in the very same video, as others have pointed out). Not in a “this happens to me at least once a day” way – it’s absolutely standard for cars to pass like this pretty much every single time I cross the road in the presence of a car. They either keep going without slowing if they decide that they’re going to just miss you, or if they are forced to stop when you cross, they then rev up and scrape by you as soon as you’re a micrometer out of the way, even when you’re still very much on the crossing. I’ve had people do it when my small son is crossing the road holding my hand, nearly hitting him; I’ve had a large lorry do it to me while pushing me son in a pram across the road.
If people did what the pedestrian in this video did to all the motor vehicles acting like the cyclist, they wouldn’t get a lot of outraged sympathetic media attention, they’d probably be taken away by the men in white coats. Yet it is incredibly prevalent and far more dangerous.
(The cyclist was still a tool though).
