I don't really agree with driving under the influence of anything. I don't care about individual reactions and all of that garbage, either.

That said, there are times when it's necessary to get from point A to point B, and a car is the best way to acheive that goal. On acid once, a friend and me decided to go to another friend's place.... needless to say, we got lost and distracted. A 5 minute trip turned into us going to play at a park, go to wal-mart, and actually loosing our bearings several times. Quite fun, but I can't even imagine what would have happened is someone had hit me or vice versa.

The problem isn't how well you can drive when fucked up, it's how well other people on the road can drive. I trust myself to handle my vehicle well when I'm fucked, but I don't trust other drivers on the road to not hit me when I'm fucked up. I couldn't imagine getting hit.... you'd get fucked over, because you're high. I don't like the sound of that.
