Obviously it's not feasible to have every parking spot pull 13KW, they would need to coordinate to manage load. The core thing is that you're assuming that every parked car arrives in the evening with near-zero charge and needs to be full in the morning. This is not the case, cars are parked 95% of the time. They can charge at work on in garages too - useful for solar power peak supply. Let's do some napkin calculations: 95% = 1 hour per day of use for 23 hours of charging. Let's assume that's 100km drive in that 1 hour, 15Kwh for a typical EV. So on average you need 15/23=0.65KW per car, not 13KW. There's 285 million cars in the US, so you'd need 4.3 billion KWh per day for full electric. Currently US generates 11 billion KWh per day [3].
