No, one car will suffice for those who drive less than a few hundred miles a day, as the battery can be recharged overnight with a Level 2 home charging station. For long distance travels, plug-in hybrids will continue to be offered for many years to come. I explained home charging reasonably well here: https://www.nytimes.com/2019/07/11/business/electric-vehicle-home-chargers.html?action=click&module=RelatedLinks&pgtype=Article Paul
