I don't see many people…
I don't see many people state the obvious - you can charge for free using a standard outlet switch. I've had my model Y for 3+ years and never installed a level 2 or 3 charger at my house. Level 3 is ridiculous anyway, you don't need more than 30-50 amps to charge overnight so the person thinking they need to spend $3000 to upgrade their circuit breaker to 200A is overkill unless you're running some kind of transportation company out of your house.
Is plugging in to the standard outlet slower? Absolutely. It's about 4mph recharge vs 25-30mph with level 2 or 750-1000mph with level 3. But I rarely need to super charge unless I'm going on a road trip or forget to plug in at night. I even have time of use electric rates so it's about $.05/kwh when I charge from 9pm-7am.
