It’s pretty simple, I go out to a dinner with friends or work, I see a glass or wine or beer for every seat for the most part, no Ubers in that town, don’t see a single cab, repeat this over many occasions over the years in many cities.
You do know that one beer or glass of wine will not put the average (or anywhere close to average) person over .08, right? Even two normal beers in an hour won't. A pint of 7% IPA won't either.
