Yes this is all my opinion and there are references that would debunk at least some of this. I agree that speed has a part to play and some speed limit changes are appropriate... I maintain its still a lever pulled far too often.
Agree with you on this one - but in lieu of comprehensive driver education (probably the biggest one as it's far too easy to get and keep a license in NZ and most drivers here suck), wholesale changes in driver attitudes (good luck), massive investments in physical road safety (show me the money), it's about the only lever we can pull sometimes.
