When someone is driving up my bottom in a 30mph limit (usually in a Corsa or some other POS) i still find it deeply satisfying dropping into 2nd just before the NSL and watching them vanish in my rear-view mirror.
This is one of my favourite things, I was even doing it to the Mustangs on NC500 trip when in the BMW as obviously from a low speed the M3 gets up and goes a lot quicker due to the light weight and SMG. Lets just say the Mustang owners were very surprised and it got nick named the annoying wasp because when behind a Pony it was always on the Pony's backside ready to sting.

But yes a favourite, though sometimes you find certain car owners really dislike you doing this so the moment you arrive at the next 30mph zone, doing 30mph these freaks catch up and then do a dangerous overtake in a 30 and carry on driving maxed out. It is normally people in black smoke pouring diesels, no doubt the kind of owner who thinks his 2l diesel is quickest thing on the road and drives it flat out everywhere.
Traffic light grand prix I rarely bother as 90% of the time road conditions / traffic do not allow for it safely, but on the odd occasion where its safe to do so then I might oblige, but most other cars that pull alongside either have no interest or just want to hear it rev and hang back anyway just to listen to the glorious soundtrack coming out the backend.
