Zoom out. The idea is that if you can get all vehicles onto the electrical grid, then you can transition these vehicles almost instantly to use better and better sources of energy as technology evolves. This is because you can change the composition of the electrical grid (it can be powered by wind, water, solar, nuclear, etc). It makes the energy source fungible as the grid becomes the delivery mechanism. Once vehicles are hooked up to this electrical infrastructure, we gain a lot of leverage as a society to move collectively in a better direction. With ICE, there is only 1 viable fuel source - gasoline. Once an ICE car is built, you cannot transition it to be powered by anything else. Squabbling about carbon break-even points of individual car purchases is missing the forest for the trees IMO.

Not much convinced: we have different kind of nearly-identical ICEs vehicles burning a certain range of chemicals like: petrol, diesel, alcohol, gazogene, synfuel of various kind (from ammonia derivates to modern biodisel) to liquefied petroleum gases and methane. For EVs we have just variation of lithium battery tech on board and few classic ways to produce electricity to recharge them. It's not different. The different part is in performance terms and in scalability terms. Can we produce AND RECYCLE batteries for any personal vehicles and eVTOL? I doubt and I'm not alone.
