Big John,
(Bear with me for a bit) when a few years my brother-in-law-to-be (lives in LA, originally from Lancashire), and my liittle family were visiting my spouses' mum in Lancashire he was a little surprised that when I slowed down to 85mph on the M6 when about to overtake a police car; particularly so as the fuzz didn't mind.
Which was fine, we were going a bit faster than that previously, thankfully I had very good vision at the time.
Many folk confuse speed and safety, one of my main beefs in the UK is when it is pissing down big time is how eejits in lanes 1 & 2 bunch up to an absurdly dangerous degree; which means I can then safely exercise some Wellington owing to having x hundred meters emptiness in front of me in lane 3...
Cheers,
Jay
