It is important to have a EV option for all high milage vehicles.That's probably the wrong metric too. What you really want to capture is miles driven (estimating fleet utilization rate by energy type). Even then some EVs are more efficient than others. Makes less difference in Norway who's grid is almost 100% renewables. In a country like the USA, you could use the 'carbon intensity' of electricity but there's a lot of wide error bars by the time you get to a single number.
Still, the ONLY thing that matters is grams of CO2 emitted, which tracks most closely with bbls of oil sold, tons of coal, and cubic meters of natural gas. If that number continues to go up, we're no where near the tipping point.
The fuel and maintenance savings really stack up for high mileage, hence it will not take much to get buyers over the line.
Then those high milage vehicles have an outsized impact in reducing emissions, and oil company profits.
In this context the Tesla Semi is important, it will be great when they are driving around in high numbers. And great in every way, lower emissions, less noise, cleaner air, faster traffic.
