i'd guess to them any kind of wheel spin would be considered as "hooning" "burnout" etc
having said that, i do think some cops are considerate at times.
once at the lights on a very wet day, on the tram tracks and right next to me at the lights was a marked cop car. i took off and rears starting spinning (not intended ofcourse) the cop just looked at me and drove off... on a different day/different copper and i woulda probably got done for it
you cant generalise on anything these days...
