I think the sentances they are given are far too fair!
Anyone who goes out on the p*ss, an then drives home, is scum in my eyes! (waits to get shouted at).. sorry but its my view on the matter.
As for drinking the night b4 an driving the next day i've not thought about that one If i still felt p*ssed or abit funny, there is no way i would drive, wouldnt want to risk hurting myself or more importantly anyone else
