It's meaningless to compare a small city truck to something like a full-sized truck, they are totally different classes of vehicle. I get that ford doesn't make a small electric vehicle, but that doesn't make the lightning the "closest offering".
I don't think you can actually buy one for that. They were tacking on an extra 10k as soon as they came out and eventually just moved the price up by like $5k and they still generally sell for higher than that.
No, that's the point, it's filling a niche that basically nothing else does right now. The closest alternative would be a small electric car paired with a small utility trailer. Something like a Nissan Leaf and one of those $500 trailers from harbor freight. Which added up and with discounts probably costs fairly similar to this.
