If we’d never thought of carting a huge vat of inflammable liquid around with us a century or so ago, the notion of doing so now would probably seem vaguely ridiculous. Electricity seems a natural choice for propelling a car, offering near silent drive, no tailpipe emissions, mechanical simplicity and stacks of easy torque. The California Air Resources Board began a big push towards zero-emission vehicles in the early ’90s, eventually seeing Tesla surge to the fore. And yet there’s really only one volume-selling mass-market electric car available, the Nissan Leaf, which passed 300,000 global sales in 2018. And electric cars currently make up 0.0004 percent of Australian car sales. It’s likely to be legislation, rather than buyer behaviour that changes this.
