It already exists in many places with 110v. Just look around and often newer lamppost installs have plug on some if not all of the posts.

A small town adjacent to my home town (The latter being too poor to have street lights, and yes, we did walk to school in the snow. Uphill. Both ways.) has 110V outlets at the base of each street light. Helps with the Christmas lights each year.
Anyway, before they built SCs relatively nearby, those street light 110V outlets were my fallback option about 3 years ago in case all other options (ChaDeMo, L2) fell through.
Loved getting the question, "How long's it gonna take to charge when you're plugged in across from the Grange Hall?"
"Oh, about 3 days if the circuit doesn't blow and take the town down with it." Sometimes I could even manage that answer with a straight face - hey, it was half accurate.
Then I got a visit from a concerned-looking town manager. Yep, can't make this stuff up.
Never did have to use those 110V outlets, but I did elsewhere (in the rain in the middle of the night, not that I remember it vividly or anything) when an SC was completely down (and not marked as such in Nav).
