I see people sleeping in Teslas at the charging station that is right next to a gas station on my way home from work. I assume they are apartment dweller Tesla owners who need a charge.
I don't have enough juice left in my current electrical panel to install another 220/230V breaker. Typical home built in the past before the big increases in power consuming devices. I'm sitting here in my home office with 3 monitors and a laptop. My wife has 2 monitors in her home office. Finished off the basement, multiple TVs, kid's electronics, IOT devices, ..... The average home is leveling off but the increase in power consumption of misc. has resulted in around 10-20% increases in home electricity use. New more efficient electronics help until you add more each year.
I've though about looking into another line and breaker panel for the garage to handle 220V heating and welding. I would definitely need it for charging an EV or two.
Data centers are the next big load growth for utilities. Projected to need up to 12% increase in the US power supply in the coming years. EVs would have been a similarly large increase, but I don't think they will take hold without mandates.
