Fred99:shk292:Sorry - NPR is number-plate recognition, I thought the term was used above. It's common in other countries and makes more effective policing of vehicle and driver compliance much easier.
I'm less sure about the wide demographic, and it would be very interesting to see an annual summary of serious accidents, their causes and contributory factors. I've never seen this but I have a hunch that sober, drug-free, seatbelt-restrained drivers in fully compliant, insured cars will form a very low portion of the statistics
I thought they'd trialed NPR in NZ a year or two ago. IIRC it may have been shelved over privacy concerns.
I share your hunch.
There's this system being put together:

After a (very) quick look at incomplete data, I'm no wiser.
Putting stats together when there are always going to be contributory causes - and probably multiple ones in each injury/fatality incident- and trying to allocate % causality etc for each of those many factors... Makes my head hurt thinking about it.
And this is exactly why these stats are pointless.
On paper you see 3 digits and go omg something must change.
What wants not really quantifiable is how many were related to something controllable or uncontrollable.
Leaves the gate open to make rash changes that really hold no actual improvement.
For arguments sake if we say 20% is speeding, 30% is substance abuse and rest is stupidity or freak accidents then you can sure go hey let's target that 20% it's still a big number.
But we have already done many things to reduce this. You start getting to the shrinking benefits to costs.
No doubt we will go down the path of those again simply because they are easy.
Personally I drive Auckland to Hamilton every weekend. I honestly don't often see people doing the dumb until it gets to the single lane areas where folk can't just pass and go on their merry way.
I'd say about 80% of people along there slightly speed. 110s(by GPS) is the normal even for large trucks but... It works. There is always room to pass the lorrie or whatever else!
But soon as I'm back in Auckland it's dart through the traffic! Must place race cars! No consideration. Wanna guess where I'm generally stuck in traffic due to accidents?
To be clear, I'm not saying speeding is OK. Simply questioning if it's actually what needs to be focused on.
