Driven over the limit the next morning yes.
Got in my car pissed no.
If you look back, i actually gave him some advice.
I can't see how this is any different morally. In fact it could be worse because when you're drunk your common sense tends to go.
That's not saying that drinking 8 pints then going for a drive is ok, or it is the same as driving over the limit the next day, but the point about the limits is that when you reach them they impair your judgement.
