Paying fixed penalty notices

Pleased to hear it as I am worried about endorsements on driving licenses for cycling offences. I think it can happen but have never been asked for my driving license yet and usually don't carry it while cycling.

Reminds me, this does piss me off.
A mate ended up with points (think it was 1 or 2?) on his commercial license for 'excessive speed on a cycle' I.E. he was hooning down a hill doing maybe 35mph on a push bike. I was also there and probably going faster, on a ropier bike, in a dodgier manor, but because I was 15 and didn't have a car license then they couldn't do jack.
Points on his license which could make it more expensive/less likely he can get jobs driving his HGV in a more professional manor?
