This driver was triggered into more than cutting in by the actions (however legal or innocent) and reactions of cyclists.

Remove the trigger, then there is no 'chase'.

These 4 riders would not have known about the previous incident, nor anything else about this driver. They made their decisions, this drivers trigger was pulled, and here we are today.

Can I be sure that the driver would have just kept driving after that first traffic light if the riders stayed behind him? Of course not. However, without something to set of his 'hair trigger' perhaps it might have been OK. The incident with the tyre iron you mention had a 'trigger' for our driver too, and once triggered he wasn't going to stop.
