Not to gang-up on you Jon,
Not to gang-up on you Jon, but I must point out that your entire argument; "I support the intelligent development and delivery of electric vehicles, but they must stand not on subsidies, but in the free marketplace," is based on a false premise. Your premise is that there are no subsidies provided to the petroleum industry.
The "free marketplace," which the petroleum industry is in, is current loaded with direct subsidies like free military protection (U.S. military is also their largest customer), avoid taxes so well that they get refund checks from the U.S. Treasury and it's customer's pay the expense of the pollution which is caused by their product. Which industry is REALLY being subsidized?
Electric vehicles are viable now, we humans just don't like change, even if it's good for us. Try going vegan.
