What was the stupid part? Stopping production — or starting it in the first place? Who was the stupid party? GM for attempting to build an EV, well before its time — or the government of California for creating a mandate for “zero emission vehicles”? Who was stupidest — GM for actually manufacturing an EV; or critics (such as the producers of the propaganda movie about killing the EV), who were harsh on GM, but didn't criticize manufactures who never even attempted to build an EV.
EV1 had an incredibly sophisticated chassis and body, for the time. It was a very expensive vehicle to manufacture (estimates are $1 million/vehicle actually produced, and no clear way to bring the cost down to an affordable level, through mass production). The problem was with the battery technology of the time. There simply was no way to manufacture a viable, and affordable EV with lead-acid, or NiMh batteries.
You left out the fact that ALL electric vehicles are solutions to a non-existant problem.
