"Carmakers are dictating what we should drive instead of consulting the public"
No, one of the reasons an Ikea plywood car could not be sold is regulations. A plywood car that is legal to sell for on-road use in most jurisdictions would cost more than a current car, because, obviously, if plywood was cheaper we'd use that.
You are right in some ways, car manufacturers mostly consult with likely new car buyers when clinicing proposals. So it becomes a self selecting circle. They say they want everything run off a 12" ipad screen, whereas you and I know damn well that in 5 years time a set of traditional knobs and switches are at least fixable, even if not more reliable. We don't want 40 profile tires because we have to pay for replacement tires, and wheels when they buckle. But we don't buy new cars so we don't have much of a say.
