This implies it's a consequential cost. Building with tactile controls would take the (already considerable) purchase price and boost that high enough to impact sales.
If tactile controls were a meaningful cost difference, then budget cars with tactile controls shouldn't be common - in any market.
Are controls uniquely important, though? There are hundreds of things in a car that could be made better (more durable, longer lasting, better looking) for just $10 to $100 extra a piece. But it adds up.
It's not just cost, though. The reality is that consumers like the futuristic look, in theory (i.e., at the time of the purchase). Knobs look dated. It's the same reason why ridiculously glossy laptop screens were commonplace. They weren't cheaper to make, they just looked cool.
