Honestly I think most people can live off 120v, unless you drive more than 100 km a day, have experienced two family's ev daily experience over the last year. Over 45000 km traveled between two EVs. Charging with 120v is totally fine, maybe the occasional 240v charge if we drove extra that week. But that's like once or twice a month. Plus you get to laugh at the pick up drivers trying to floor it to pass you.
