OK, understood, maybe leaving a car charging overnight and not moving it is fine... perhaps...
But leaving the car multiple days plugged in... not sure about that.
It's just a really pain when someone else comes along with a really low battery and there is several cars plugged in not charging.
When I had only our Nissan Leaf with it's fairly limited range it used to really annoy me, but with a LR M3 I don't worry as range anxiety is all most gone.
At the mo', it's the ICE drivers with range anxiety ;-)
