Why would I be unhappy? Consider this:

I drive to the mall.

I plug in the slow free charger (maybe ~3500W) as opposed to the paid one at >20000W.

Two hours later I have, say, about 7kWh topped up on my battery.

I now have restored about 40km range, so my 30km drive to and from the mall would be entirely restored.

Even better if we could somehow trunk my space’s 3500W of panels with the ones covering the combustion-driven car next to me. And the empty space to my other side…
