Earlier quoted context omitted.
Grid capacity is what blocks EV market share and will continue to be the blocker for the foreseeable future. A 2 person apartment where I live will consume ~400kWh of power in a typical month. Charging a 100kWh battery twice a month per person would double the power usage. We don't have the power generation, nor power delivery for that, nor will we have it for some time.
Not really, a car serves for ~15 years, so even 100% EV market share will mean only 6% or so annual replacement rate. Plenty of time for grid to adapt.
Edit: Average car age is < 12 in the US, not 15.
