What good is it to have a house to plug your car into if there isn’t available power to support the increased demand?
How many new power plants have gone up to supply those homes with power they need?
You and I are in 100% agreement. I posted on if EV's can become popular in a red state (here in Alabama they might can from a sense of "we built that"). But as far as it actually working well if it becomes popular, you're correct. The electrical infrastructure would need to improve.
In fact, we've had to shut down coal plants and we're in the middle of replacing them with natural gas plants. We're currently using natural gas plants originally meant for reserve power only in higher use to give us sustained power (to offset what coal was doing for us). So we haven't had the blackouts ... yet, but we have little in way of reserve power. And power costs are going up (by all the demolition and construction costs being passed onto consumers, and by the high cost per cubic ft of natural gas the power company pays being passed onto consumers).
Me personally. My wife and I own an EV car and an ICE pickup, do most of our driving in the EV, and have 85% of our power supplied by our home solar (basically the solar provides way more than what the EV demands, so we're pulling less from the grid than we did before). But we're weird. We're not trying to save the world from cow farts or such. We're trying to make ourselves mainly energy independent so that we avoid most of the high energy costs the Dims keep throwing onto us. Plus our driving dependencies are now diversified: if the Dims mess up power we have an ICE pickup and solar, or if the Dims mess up gasoline we have an EV to depend on.
