Re the suggestions that NZ switching to driving on the other side of the road will save lives and money, I can't really see how it would do either.
Saving money in the long term - perhaps, after a substantial time to cover short term costs, and even then the financial benefit may be somewhat dependent on other countries in our region with vehicle markets that affect ours (Japan, Australia) switching as well.
Saving lives - also questionable. More than half of all tourists to NZ come from nations that drive on the same side of the road as us. Road quality and lack of median separation is probably a far greater factor than driving side.
Getting the discussion somewhat back to EV news, I've had a PHEV (Outlander) for one month now. I guess you can call that wading waist-deep in the shallow end of the EV pool without fully taking the plunge. Well, perhaps neck-deep because it has eliminated almost all our fossil fuel use.
So far it is reducing our petrol use more than 99% but once we start taking more extended trips (and if we didn't, eventually the car computer would periodically force some petrol use anyway to avoid what's in the tank going stale) I estimate it will probably be about a 90 to 95% reduction.
