It's really interesting watching videos of emergency responders in my country (the UK) either showing how their advanced driving looks in practice, or in later stages of training when they're explaining their thoughts to an instructor as they work.
Their progress through traffic is markedly faster without greatly compromising safety. They aren't making violent manoeuvres, they accelerate pretty aggressively but other than speed limits they aren't breaking many rules that apply to everybody else. They are paying a lot more attention to the environment and applying excellent judgement from what they learned. For example rather than weaving through traffic like a Hollywood movie, they take clear bold lines and hold them, which gives them better vision of what's ahead and more options when things go wrong. It's doesn't look as flashy, but it's very effective.
So for example https://www.youtube.com/watch?v=RmGDpUnlMas is people learning to drive an ambulance in an urban environment, so, they're under blue lights with a siren, they're authorised (while learning and after completing training) to exceed speed limits, and break various other rules, but they're being trained to do this safely (or at least, more safely than most people probably drive normally)
https://www.youtube.com/watch?v=wjkBchxT5kw is a solo, commentating live on his driving in a response car rather than an ambulance, again he's be authorised to break the rules.
I like the second one better. It's priceless to hear how slightly he accents unFORtunately he hasn't seen me after some driver blocks him for about 28 seconds despite blaring sirens.
Anyone operating a machine in a way that doesn't leave much margin is, in fact, not skilled at operating that machine.
