It doesn't help Home Brewing in any way.
I don't think this promotes responsible behavior. It makes it easier and more likely for people to consume alcohol and drive, which I don't consider a good thing.
I think this is terrible if they sell to people who will then drive. Having 2 beers has some impact on driving, even if one is not legally drunk. This will lead to more accidents and injuries/fatalities. I don't care if the driver kills themself, I do care if they injure others or their property. (Its the opposite of invividual responsibility - they are being irresponsible since they can't undo injury to others)
