Electric hot water heater = 20 amps
Electric stove = 50 amps all burners on and oven
Washing machine = 15 amps
Car charger = 50 amps
Total = 135 amps
Standard residential service in the US = 200 amps split phase @ 240v
Whats the problem?
Add in the 80% rule and 200amps doesn't go as far as one might hope in a gas free-house.
None of those devices pull the rated amount continuous except may the car charger which can be adjusted for less draw / longer charge time if needed.
Simply scheduling car charing for overnight would eliminate any issue, even so there is plenty of headroom on a typical residential system.
Requiring new builds to have even more electrical capacity and more robust incoming infrastructure is a win-win-win situation and hopefully that is what code & consumers demand.
Its not like its year 10'000 and we polished technology, infrastructure and everything to the max physics allow. For example you can easily break whole internet if significant portion of its users decide to download something relatively big at the same time.
If you can stick to plugin hybrids and go without AC during a power outage...

Internet, Misc = 1 amps
