So much has already been said and written about drink drivers - despite all the needless road deaths, publicity, campaigns, public naming and shaming, lost licences and lost jobs, people continue to get behind the wheel while over the limit. We named more than 40 local drink-drivers in Wednesday's paper - that's from just one month.
But with statistics this week detailing road deaths nationally and locally for the year and for the holiday period, another mystery raises its head.
How on earth are people still dying because they're not wearing seatbelts?
Of the 18 people killed on New Zealand roads over the official holiday period, four could have survived, said police, had they been wearing seatbelts.
Isn't putting on a belt as much a part of starting a trip as taking off the handbrake?
