That all sounds good on paper, and in theory I agree with this. However, the guilt springs from the knowledge that your actions can have profound effects on someone else life. Yes, I know their driving can have a profound effect on my life and others, however, it still doesn't make it easy to make that decision to change theirs.
Add to this the fact that I am not anonymous. I have to take into account the effect of pursuing drivers like this, whilst taking into account how the less scrupulous people who, are anti me and cyclists in general, might react towards me and my family.
Anyway, having dealt with First Glasgow before, I trust them to take appropriate action, whatever that may be. At the very least, I'd be surprised if she was allowed to drive a bendy bus again....
