I don't understand that mindset at all. Why should you be able to drive after drinking? Don't you think that people who consume much more alcohol and then drive are also under the impression that they are fine? The law must be based on scientific evidence of the effects of alcohol not on people's subjective judgement of how much is safe to drink for them.
I agree with all the other points though that it all needs to be enforced, and that careless driving is an absolute menace - see it every single day.
