Here's my concern

If I don't own a parking spot because I live in an apartment I can't charge my car while I'm home.

Can I use a public charger? Well my car needs a couple hours charge every day or two. I'm not going to sit there and wait. I'm going to work or sleep or otherwise get on with my life. Now that charger is unavailable to anyone else. To install a lot of them in a sizable parking lot is going to be expensive and require a big power feed to the site.
