In some countries where Governments have taken strong action by way of introducing EV subsidies etc there has been a much higher uptake of EVs relative to petrol vehicles than in New Zealand. You could say this is because some overseas Governments have seen this as a Government problem that can help be "solved" by specific Government action, such as subsidies etc. This is principally because some Governments are taking stronger action on climate change etc than we are here.
So, if Governments fail to take decisive action to encourage the uptake of EVs, then you could say that they are part of the cause of the continuing high inflow of petrol vehicles. At least NZ has introduced a policy of providing subsidies on EVs in the future, but we have been very slow to get going compared with several other countries.
At the moment, about 97 out of every 100 new vehicles purchased in NZ are petrol driven vehicles, and this situation must be of concern to the Government as that's why they have finally decided to try and do something about it! When the import of petrol vehicles is banned altogether, then we'll be getting somewhere, but the worldwide shortage of EVs and their high prices means this won't happen anytime soon.
Our governments, both of them, are not that into climate change. It stops when its a we will buy more EV's for our fleet. In NZ I'm not convinced we will go hard out when the up to 8k subsidies come in. Im talking NZ not Norway. When prices are closer to ICE and when there is a choice that will make far more difference than a small subsidy on an over priced car. And we are talking mass market cars not upmarket. The more choices will be here soon, prices should reduce, subsidy about the same time, I'd wait till then see what happens. We can't afford much that's why we say we are into CC but we don't do much about it. Talk is cheap, that's climate change in NZ as I see it
