People are quick to point out vehicle crashes where evidence of alcohol is found in the body of the driver, but are there any studies that show how much driving time is avoided due to alcohol consumption?

I know drinking and driving is bad (and so do many others), so for many of us I would wager it keeps us away from driving and many other dangerous activities. Sober me with too much free times starts thinking "lets go walking into back alleys in Mexico or riding motorcycles through the twisties." That's not to say one is healthier that way, though.
