Perhaps a more likely scenario is that there will be  a secondary industry putting new bodies on recycled skateboards.  Allows for all kinds of creative designs.  

With the variations due to temperature, driving style, terrain, speed these differences are totally irrelevant. They all have a similar range.

Every increase is good. This puts it into the range where you don’t really need the range extender, which makes the car cheaper, lighter and more efficient. My i3 was turned in after the 3 year lease ended with the original factory gasoline still  in the extender tank.
