I'm voting with the drivers being the issue as well.
Yep there are potholes, yep there are traffic light down for weeks on end, yep, yep, yep... BUT... Last month a guy drove into me while I was sitting at a red traffic light. Let me rephrase that, a guy in a Getz drove into me, without slowing down at all while I, and the fifty or so cars around me in both lanes were stopped and waiting patiently at a red traffic light and had been for twenty seconds or so already. The guy then rolled back into the car behind him and fell over twice while we waited for the popo... Drunk or drugs, don't know but it was 10.30am on a Saturday morning.
Then, last week, a 4x4 shot a traffic light around the corned from our offices. In his rush, he managed to hit a woman in a Polo on the wrong side of the road... That was when he lost control totally and crashed through the wall of the shopping centre, right next to a really bust Steers and about two meters from one of the centre staff who was taking a time-out to have a little lunch.
Twice yesterday, I slowed down and stopped at traffic lights that had gone red for me while the guys behind me just put their foot down and shot the lights. Hooting just draws verbal abuse from these upstanding citizens. Perhaps they'll be a little more contrite when they're standing over the bodies of people their arrogance and two ton car kill.
