If the cars charge at work, during the day, that will be a problem. But if they charge after midnight, when usage is down, it won't require any additional infrastructure at all, because all the charging will be off peak.

But also, home electricity usage is down like 8% in the last decade. We keep on installing energy-efficient lighting and appliances and heaters. For decades and decades, we added more electrical infrastructure because people used more energy every year; but in developed countries, usage has flattened and/or fallen in the last 20 years.

The reason people need 240v chargers is that they want to charge quickly. But the average driver can get enough charge overnight on a 120v outlet. (On 120v, it only charges about 3 miles/hour, but the average car is only driven 30 miles/day.)
