A quick google says that 26.8% of drivers killed or severely injured in a car accident had alcohol in their system. Not drinking and driving significantly reduces your risk.
That’s “drivers (excluding motorcyclists) seriously injured or killed in crashes and whose blood was collected at one of the par- ticipating trauma centers or by MEs” in 2020. There were 474 such drivers, 127 of which had alcohol in their system. But there were 38,000 automobile fatalities in 2020.
Sure, that’s why it’s important to know how risky automobiles are if you discard the cases of drunk drivers injuring themselves. I suspect drunk drivers injuring themselves accounts for a very small portion of automobile injuries, but we need to see the data.
It’s not enough to say “I don’t drive drunk, and driving drunk is very dangerous, therefore automobile risk estimates don’t apply to me.” You could make the same argument about driving blindfolded.
