I believe 0.05 is too low. I’m not convinced 0.08 isn’t too low. I’m more of a 0.10 guy, but hey, I could be wrong.
More than the beer, it’s where your head is at when you drink and drive. If you’re serious about driving decently, I know you can do it at 0.10.
That doesn’t mean you should. We have to drive responsibly.
I have driven far worse when sober than I have when I’ve had some drinks.
It has nothing to do with any safety factor. There’s HUGE money collected from DWI/DUI. They need more money in the coffers.
