A friend has a Cirrus: weighs 600 pounds dry. I gave my son a 1982 Rabbit for his first car. A sensible vehicle. Fun to drive. Simple. Now? A computer on wheels. I don’t expect an Id4 will be in the road in forty years.?
> My hopes are dashed!? ?Maybe by the time these are on the used market there will be a upgrade replacement battery that will increase the range.?
?
I feel the same way.

There are two ways to build an EV. The first is the auto company way. Lots of steel, so heavy, so it need a big motor and lots of batteries to move it. Poor range due to all that weight. Expensive due to the sheer mass of materials.
?
The second way is more like an airplane (or original microbus). Keep it small, light, and simple. Use high-strength composites, to halve the weight while keeping all the strength. Half the weight means half the motor and half the batteries for the same range and performance. Despite the higher cost of the composites, it winds up cheaper because all the rest of the parts are smaller and lighter.
