My experience of coppers living in Norolkfshire is it depends a lot on AGE, even though you can drive a normal car sensibly you are far more likely to be stopped by plod, motorcyclists even more so in my experience.
Yes around here the courts are in the plods pocket, there are a few good ones, traffic cops tend to be the soundest around here, though some picky git stopped me and discovered after spedning 40 minutes going over my cossie that my rear number plate digits were 2mm TOO NARROW, then tried giving me a ticket, he was a traffic cop(bike) so I pointed out that he couldn't and the first time was a warning only, he got well pissed when I called his bluff telling me no I can ticket you, so I just kept saying go on then.
My dad had a bodykitted rover sd1(kat kit) was their original demo car and we got stopped often, the first thing said was "now then sonny where did you steal this from", as they crouched down to see a 65 year person driving, the copper beinmg around 20-30, it was then an appology and we were on our way.
They are absolutely biassed both towards the young around here at least and the yanks.
