It's the upper-middle class environmentalists. Of course, their strategy is stupid and self-defeating.

"In an egregiously desperate move to encourage prospective Cybertruck buyers to pull the trigger, some folks are being offered massive discounts and perks, like free lifetime access to Supercharging and so-called Full Self-Driving. It's not exactly a shocking move. Tesla CEO Elon Musk said it had over 1 million reservations for the truck, and it sure looks like it only converted about 50,000 of those to actual sales. That is abysmal."

"If you're the type of person who wants a Cybertruck (gross) but has been waiting for them to get about 10 to 15% cheaper, then I guess this is a good deal for you. For everyone else, we can gawk at just how badly Tesla and Musk overestimated demand for an ugly, half-assed truck that has become a divisive symbol in ways that few other vehicles can even dream of achieving."
