A quick google is telling me that 26.8% of drivers who were killed or severely injured had alcohol in their bloodstream. Assuming that's true, then wouldn't never drinking and driving reduce your risk of death or serious injury by around 26.8%? That seems like a substantial reduction that is completely in the control of the driver.

no, you have to get everyone else to stop drinking and driving, not just yourself, to get that sort of reduction.

No you don’t. Over 50% of crashes are single car accidents. I suspect, but don’t have proof for, that that percentage is even higher in alcohol-related crashes (eg driver nods off and drives into a ditch/telephone pole

How? The 26.8% is just drivers with alcohol in their system. If I never drink and drive, I will never be part of that group. That means the raw rate of traffic fatality or severe injury is 26.8% lower for people like me (non drunk drivers.)
