1) While that does technically work, it will be pretty slow. My Tesla Model Y charges 3-5 miles of range per hours on a 120V outlet. Perhaps fast enough for most though.
2) I was just in the Canadian Rockies (with said Tesla) and all outdoor parking spaces had outlets. AFAIK they were for the block heaters for harsh winters. It made charged over night slow but nice. Any parking space had them. Cold climates accidentally made it super convenient to park and charge for long stops.
