Let's not 100% condemn the op here. Almost all of us will have labored the desire to 'spank' some tosser in a Corsa.
Questions here for me are more like...
Is he lying?
If so why?
Was he attending the meet to race and behave like a deplorable twat?
Was he passing for any reason (chips, mates chips, massage, whatever) and happened to decide to 'spank' a tosser?
If so, has he lied just to make the story that he was 'just passing' seem more plausible?
