Yeah, I know that driving home was the wrong thing to do as I knew the prick was following me but I'd not actually done anything (even in response to provocation) to justify any form of altercation.
Driving around until he got bored would've bothered me immensely.
You never know who's out there though. A few years back someone came at me at the traffic lights with a claw hammer. I ran (drove) away pretty damn quickly that time
My son's currently out on his first driving lesson

(17 today!). I've just insured his Polo 1.2 for him and we'll be heading out later. Hopefully his first few years on the roads will be less eventful/expensive than mine were.
