This article by the World Resources Institute shows how important it is that there is an infrastructure that enables individual decision-making to take place. For example, I’ve been vegetarian now for eight years, and it’s much easier to remove meat from your diet these days even than when I started to so in 2017. Likewise, because of investment in EV infrastructure, these days it’s unproblematic to own or lease an EV.
The idea of supportive infrastructure, policies or incentives rings true. My own situation makes an EV difficult: cost of an EV & charging when tenement living. My current job needs a 40 minute commute by car, or a couple of hours each way by public transport. I hope that is offset by not having a car till I was 49.
