Actually I think the "average Joe" here used to think the late 90s EVs failed. When I got a used one, various people said "didn't they stop making those because they didn't work?" They didn't follow the saga and assumed product ended=product failed.
WKtEC opened some eyes, but it is the new products (e.g.: Tesla Roadster & Nissan Leaf) that are getting the mainstream interested. The EVs of the late 90s were a blip and a distant memory even here in California.
