The article is full of holes. But no matter what size your breaker panel is, it does NOT determine the size of the service you are getting from the power company. That is determined by the transformer that serves your house.
Most residential services have a 15 kVA transformer which is 240v 62.5 Amp. Some subdivisions and urban homes share a larger transformer, up to about 300 amps, 240V. I’ve seen up to 8 homes share a transformer that size, they usually are the green pad mounted type instead of the gray pole mounts.
But infrastructure will come as EV’s become more numerous, just as gas stations and roads bloomed on the landscape as cars and trucks increased in number.
The real elephant in the room is not the infrastructure issue. The real elephant is that gasoline and other volatiles are a hazardous waste by-product of oil refining. Oil refining provides so many products that are important to us like plastics, textiles, lubricants etc. As long as we want those other products, oil will be refined and gasoline will be produced.
I believe in the end, there will be a balance of EV’s and ICEV’s. Almost all multi-vehicle homes will have a mix of both. Single vehicle households will probably have a hybrid or plug in hybrid. This will make the most economic sense in the long run.
