Tesla is not the first one to try this. I do remember renting a Prius once without instrument cluster behind the steering wheel, instead a speedometer in the center of the dash. While I disliked it, I got used to it, i.e. it became tolerable by the end of the week long rental period. That said, young people today have other opinions. My son likes the Tesla's no instrument cluster behind the steering wheel - he would not pay $199 to add one (I offered to install it for free). I suspect he would pay to not have it, so I think he would appreciate being able to get a car without an instrument cluster behind the steering wheel, especially if it's cheaper.
So while old geezers like us may hate the idea of no instrument cluster behind the steering wheel, I applaud Hyundai for offering their customer a choice. And yes, it costs more to add a display, so that cost is added. And not, you cannot just add up the cost of parts. I ran a business selling a hardware product (non-automotive) and pricing the product at 2.5x the landed cost is the break even point after including returns, lost/stolen shipments, fraud, warranty replacement, etc. I also worked in the consumer electronics design, and IIRC every $1 of parts costs ended up $10 in MSRP of the product.
Ok, now let's talk about the stupid touch controls for everything - insert old man yelling at the cloud meme.
