However drinking a few beers does not impair my judgment. I have done Calculus homework after 9 beers.
Calculus is math it has nothing whatsoever to do with judgment they are completely unrelated. Reaction time and mental acuity after even one ore two bears is reduced regardless of your feeling on the matter this is verified scientific FACT, no one has EVER measured an improvement in reaction time after consuming alcohol in a blind study.
I'm 100% with Nigel, it doesn't matter what you 'feel' science has proved conclusively that your ability to react to the world around you and your ability to control your muscles declines after even a beer or two. What you experienced was simple luck followed by the adrenaline rush which in your altered state you perceived as the 'superman' feeling that many mind effecting drugs cause in people.
One very very important thing you need to take into account is that the risk when driving a motor vehicle of getting into an accident is actually incredibly low to start with. The isolated incident in which you took part doesn't prove anything at all, in fact if you'd simply panicked and not moved you can't prove that an accident wouldn't have occurred anyways because that's not what happend and your opinion on the matter is highly suspect having obviously been in a fight or flight situation and under the influence of alcohol your judgment was guaranteed to be affected, you're looking at it based on emotionally fueled lenses..
The reality is that what you did was wrong, you're lucky there wasn't an accident. It had nothing to with alcohol improving your driving ability and it's a crime that you should even think that let alone say it to someone else in public as it WILL kill someone to perpetuate that kind of mentality. You can feel or think anything you want, science has already prove conclusively case closed no comment applicable that you are wrong.
This reminds me of a comment BrownOut made last year sometime saying that headphones connected to a musical device that he listened to under his helmet on his motorcycle actually made him a better driver. It's not drinking and driving, but there's no logic or sanity behind the statement.
