I don't know what the batteries in those car are designed to
accommodate, and clearly neither do you. It's going to be a lot more
than 5% of the capacity.

 How did you twist my question into that?

How did you manage to post such a daft misapprehension?
Most cars are used mainly for short trips. Most people expect to use them to make long trips from time to time and pay a lot more attention to their performance when they are stuck in the car for six to eight hours.
In Australia there is a "Go Get" scheme which parks cars all over the place and if you want to use one you can book it on line and get into it by waving your Go Get" card over the sensor on the car.
My wife and I tended to book smaller cars than the one we own - where my wife had insisted on a fully adjustable front passenger seat so she could sit comfortably while I was doing my half of the driving on long trips (which didn't happen often).
