I can want three cupholders, not two, on my next car, and I want it to be a Toyota EV in purple. Not too much to ask - but Toyota has no reason to make it for me. Not even if 100 of us on Toyota superfan sites want it.
For the record, I want removable batteries and the ability to change my phone's OS. But if there's not sufficient market pressure, it ain't gonna happen - without legal force. And that won't happen if the businesses have too much lobbying power (USA), or it's specifically against government interests (3-letter orgs wanting backdoors).
