Yes you are probably an idiot, but in all fairness some of the 50 zones are pretty crazy. I know in NSW there are some 50 zones for no apparent reason (a couple of houses, no schools, wide straight road). I think it's a slight revenue raising tactic by the police.
However we have to follow the road rules and a lot of speeding just gets people killed or crippled for no reason.
But yeah try to get your license for work. Good luck!
