See the next sentence, it was pure luck that no one got hurt as I was swerving, blowing through red lights and hopping curbs. I knew I had no business driving, and I don't need a law to tell me that what I was doing was completely dangerous and reckless.
Don't you think there is a difference between belligerently drunk, as you were, and being intoxicated without hampering your ability to drive safely? If your jumping curbs and swerving you should be stopped. If you forget to signal a right turn and you happen to have had a drink or two or three you shouldn't get the screwing that is now coming your way.
