I think the underlying challenge they face is not the cars, perhaps not even the battery technology, rather it is the underlying public infrastructure of power generation.
For now 1% people or less have such cars and the infrastructure handles it fine, but what about when 30 percent of everyone driving owns one of these?
what will then happen then?
THAT and not the other questions is what continues to vex me.
I doubt Tesla/Volt/Leaf ever has 30% market share
The company’s website does say they’re expanding their supercharger technology and stations.
Getting the infrastructure in place will determine whether a mass market electric car can be viable - and profitable.
