Another solution (for some) would be to have a charging port in your parking lot at work.

Is the supermarket really the only place you don't park on the street? I realize at the present moment, it might be the only lot/garage you park in with a charger, but as EV adoption increases more public chargers will sprout up.

My point is that opportunistic charging while parked places people go already can meet the needs of at least some street parkers. I don't panic if there are no charging spots available when I park somewhere, because I'm not depending on any one single parking session to charge my car. I get a little charge here and a little there and in aggregate it meets my weekly charging needs (most of the time anyway, weeks with substantially higher mileage need special handling currently).

This is not to say it will necessarily meet your needs anytime soon; however, I think we are at a point where the relative price is the biggest hurdle to adoption. There's a lot of people for whom an EV would be practical with current infrastructure that don't have one. As more of those people buy them, there will be additional incentive to invest in public charging infrastructure. The more public charging infrastructure there is, the more practical EV ownership is for people who can't easily charge at home.
