gzt:cddt: ANZ truckometer reports that in the three months March - May, light traffic volumes dropped 4.2% and heavy traffic volumes dropped 2.2% (all seasonally adjusted). As I asserted earlier in this thread, fuel use is surprisingly inelastic... people who were speculating there would be drops of 20% were wildly optimistic.
Dunno how this data is composed. I suspect it's road samples at fixed points and probably captures relatively inelastic typical commuting as well.
Anecdotally people are driving less discretionary kms. 20% less domestic discretionary kms, dunno, could be.
The ANZ Truckometer has been around for nearly twenty years and is a highly respected measure & highly reliable predictor of economic activity. The data is collected via vehicle sensors embedded at key points in the road network. The sensors are managed by the NZTA / Waka Kotahi, who have released the data publicly every month since 2008.
There is an interesting article on it here: https://data.govt.nz/catalogue-guide/showcase/anz-truckometer
