If you're in that situation and you've already broken the speed limit so flagrantly multiple times that the courts have installed a speed limiter, that family member may well be safer waiting for the ambulance.
“There is a strong relationship between the number of tickets a person has in a two-year period (2015–16) and the likelihood of a crash outcome (2017–2019). However, the accumulation of tickets is not the best predictor of crash likelihood. A combination of the excess in speed and the accumulation of tickets increases the relative odds of a subsequent crash” [1].
So no, the person who regularly breaks the limit by 20 mph is the textbook person who should not drive their bleeding relative to the hospital but instead wait for an ambulance.

About five minutes on Kagi. There is a solid global meta analysis [1], but it’s not as simple to read and doesn’t discriminate by the speeding magnitude. So I opted for the cleaner source as it’s more relevant to the question of people who speed so aggressively and often that a judge might consider putting a governor on their car.
Also: not sure why it’s a crazy to analogise kiwis and Americans. I honestly thought it was common knowledge that folks with lots of speeding tickets tend to crash more frequently than population.
