I didn't zig-zag at all.
I kept the middle line and waited for you to move to one side, so I would move to the opposite side.
You seemed to move to the right, so I moved to the left - but then you suddenly moved to the left too, so I moved to the right to avoid you - and then you moved to the right too, so I came back to the left and just stayed there (I was like "come on, Tom, make up your mind, damn it!").
Don't talk as if I "used to drive doing zig-zags" - everybody knows that's not what I do, or how I defend my places.
And I was reffering about things that I saw before (a LOT of times) and people just keep doing it, as if they were the "nicest & cleanest" things evah - so, to me, it's just a shame to realize these people will never change.
I was just 'venting' about it - HOPING they would THINK about it and TRY to race a bit cleaner or even 'nicer' - it won't hurt them if they try...
