A paramedic leaning out of the window shouting "Get out of the way, you
self-important ****"?

Technically that's incorrect.
The law requires he shouts:
"Get out of the way, you sad, deluded *******"

But your sentiment hits the nail on the head. With hindsight, it probably
would have been a plus if someone had done the same to the self-important
****.
