The anecdote was about charging a car on a 120V 15A wall outlet, the kind of thing that a toaster usually saturates. Absolutely not about charging a car with household electricity.

Does your home have an electric dryer or oven? Use a circuit like that. Does it have that outlet in the garage or parking area right now? No, likely not. But the question is about running cable, not "introducing new stresses for an inferior solution".
