Given how different the Wench and I are in terms of body shape and preferred driving position (plus my back issues and her hip issues), the likelihood of their being a one size fits both level seat are sadly quite slim.
So it will just be each of us forever adjusting every aspect of the seat / wing mirrors, rear view mirror / steering wheel height every time we get into the car.
That would be enough to allow for replacement though. The motors wouldnât be replaced, just the battery cells. Itâs not trivial, as I said - the systems charge at different rates and can have very different cooling.
I imagine that it will take the likes of Tesla to come up with a great system, and that will gradually filter down to others, as they realise that licensing it makes a lot more sense than developing something inferior themselves.
I think that rather trivialises the challenges for categories of car that Tesla arenât active in. As I understand it, the S, X and 3 all have the bulk of their cells in the floor as it keeps the CofG nice and low. Thatâs great if youâre designing a large sedan but I canât see it working as well for a K-Car sized device and the manufacturers active in that category might want cells of a significantly different shape and size to work with the constraints of that.
