I'm guessing you don't live in urban California, where most grocery stores installed L2 chargers 5 years ago? They were intended for short-range EV charging, and most EVs aren't short range enough to find them useful. I rarely see anyone charging at the ones in Palo Alto. Some Tesla Superchargers are near grocery stores, that's a pretty nice combination. I do have one friend who hasn't bothered to install a home charger because she can use the supercharger next to her favorite grocery store.
