CRAZY DRIVERS!!, Christchurch
Seriously, drivers in Christchurch are the worse in the world, they cut in front of you, they dont give way to you, they speed, there are boy racers, teenagers with altered cars who drive like stupid and leave drag marks over the roads, and who got a speeding ticket today?? ME!!! the traffic lights turned orange and i sped up because it was too late to stop and the police gave me an $80 dollar fine...
Anyway, Christchurch has a great number of roundabouts, and some of these are double laned, so you have to be in a certain one to turn a certain way. Also most roads are single laned, so often there are people overtaking dangerously, or if you want to overtake someone often the road is too bendy or busy to do so. Still you cant always blame the locals (though I do), anyone with a drivers licence from overseas can drive in New Zealand, so there are often accidents where tourists go onto the wrong side of the road (drivers in New Zealand drive on the left side of the road).
So anyway if you are driving in new zealand, remember to get insurance!
