You could easily argue the Hummer is symbolic of the problem with legacy manufacturer’s attempts at EVs, or at least the most extreme

Rather than create an EV anyone can afford, rather than design a vehicle around the needs of an EV, rather than care about any sort of efficiency …. Take a monster of excess and just keep adding thousands of pounds of batteries until it works. And you end up with more of a monster of excess: excessive price, excessive consumption of batteries/materials, excessive weight. You have a vehicle designed for people who values excess, made it even more excessive and expensive, and try to sell it to customers in the name of efficiency and reduced pollution. Of course it won’t work.
