Tesla is the only one that has "burned their boats" and fully aligned their corporate future with electrification.

On that spectrum there's Tesla, a bunch of Chinese firms like BYD then a big gap before firms like Jaguar, Audi, Volkswagen all of whom are selling products that Tesla can rightly attack as being the past, not the future of transport.

I think every bit helps, including efficiency, smaller cars, public transport, city cars and non plugin hybrids like Nissan's eNote range but Tesla is setting the pace to a large degree at the moment.
