All I am saying is that "simply" is not really that simple. Tesla made a very good choice with their battery design. For them it IS simpl-er. It took a clean salte for them to do it.
Handling is not an issue for the S by virtue of that choice. There is a certain material inefficiency to make the car larger for something it only has to do occasionally. It is a choice I would not make. I would buy a car that does most of my traveling in its standard form. When on a long trip, I might rent or drive ICE. I used to buy careworn used cars and rent for trips to save money. It makes sense.
