For 8 months I've been traveling in the US[1] and Europe[2] by bicycle. Most of the time I was camping and McDonalds was the most convenient place to charge my phone. I found that I could easily spend 2 hours per day there without getting bored. I didn't have a stove, so it was my warm meal on most days.
I suspect a lot of underemployed Americans could adopt a similar routine to get their cars charged.
