Yes, and definitely more wrong for him to taunt the driver after that.
In any case the world will be a better place if we all just try to understand each other and give each other some space.
For the Vivocity case I think the cyclist was clearly in the wrong. So the car should not have continuously horned him (as claimed by said cyclist) but there is no need for him to insist that he is right and taunt the car driver.
I don't know if anyone remembers this case, but I remember it because I thought it was a relatively sad way to go.

So what if the motorist at Vivocity had just experienced a fit of rage that Keneth can definitely understand? And just happily rammed into him? So the motorist would have gone to jail, Keneth would have died, is it all worth it?
