We all know larger companies spend money on PR. They can buy "a few" EV vans even if the equation goesn't work and publicize it as how they are "stewards" of blah blah. So, maybe they buy 100 such vans, it gets in the news, but they have 10,000 ICE vans (and will for years). There also is "reverse PR" of course, I've seen memes of an ICE van labeled a TESLA service vehicle, and I'm sure they exist today as well.
The sole reason I'd buy an EV would be my calculation it's the best vehicle for us, period. That includes tax credits of course. a thing when will mostly benefit people of means who could buy one anyway. Regular folks will be buying used or leasing ICE vehicles until the equation really is unbalanced.
