Hi Roadie,
It sounds like you're experiencing the worst NZ has to offer there! I don't think you'll ever escape the bad drivers, there's plenty of those no matter where you go although around here (in Hamilton) seems to be limited to the few rather than the many. The only vandalisation I've ever seen is tagging, and thankfully that seems to be slowing down with all the recent docos reporting taggers to be morons

.
I think the litter situation where we are is great. You hardly ever see litter, and what litter there is, is usually recently deposited mcdonalds wrappings by some loser from their car window. It gets cleared up pretty quick though.
Maybe you need a road trip, to go and look for somewhere else to live. I do honestly believe that what you're experiencing is the bottom of NZ's barrel.
