Few months ago.

>decided to function test my new clutch I just installed
>My motorbike isn't taxed or insured at this point
>wait until 9pm to test drive around my quiet residential area when I know there won't be any other cars
>on about 2nd lap of area( clutch is great, butter)
>suddenly 3 cop cars drive into the street
>quickly do a 360 degree U-turn
>ride straight to my parking spot, put the cover on my bike and chain it up.
>take off my helmet and jacket then hide my helmet under my inside out jacket
>walk nonchalantly back home

Luckily it turned out they were just there to arrest some combative gypsy and probably wouldn't have bothered to run my plates.
