I'm not defending drink driving, but I think there is a common misunderstanding (from people of every generation) on what you can legally drink and drive.
From that report, it would show that he had 2-2.5 pints roughly. I know a lot of people who would have that and drive. "It's ok, it was with a meal", "It's only a short drive home" "I drank them quick so it won't be in my system yet"
Even drinking 1 pint would in theory put you over the limit. Messaging needs to change that you shouldn't drink anything. Allowing people to drink a bit, ends up with lack of clarity.
We all make mistakes, sometimes because we don't think, sometimes because we don't know any better and sometimes because we think we can get away with something.
Sydie needs to learn from his mistake and I would suggest helps others to know better too.
