I questioned myself today - whether I was over reacting.  Then he drove past, revving just to hear the backfires on the over-rev.  That soon made my mind up.  He's obviously just an anti-social tit.  Unsurprisingly, speeding every time he passes (30 zone), loads of kids about etc.
It's a little like the Indian call-centers who keep calling every day at 7, just as I get the baby to sleep - at least the phone has a silent night-mode so i can filter them out.  Even the most innocuous thing, at the wrong time, for a period, is enough.
No intention to waste police time, just wondered what the score was.  Will try and speak with him first.  The exhaust on my car is modified, so I totally get it - but I wouldn't  behave like that - have some respect for others ffs.
