Another problem is making the thing automated. The idea is to make it so that you pull in, and a machine takes out your battery and puts a new one in. All with little error.

I imagine one of those automatic mechanical car wash machines -- y'know those ones at self-wash places and gas stations that always seem to be broken? -- except they do batteries and they're even less reliable because everyone is using it.

I can't wait to get feedback from the tests in Israel and the others.
