Survivorship bias, information asymmetry and product design is at play here.

100% rational and 100% informed consumers do not exist. There's both information asymmetry between manufacturers and consumers. I'm sure there's man fatal accidents that can be traced back to faulty components and improper design that gets covered up by manufacturers. The Volkswagen emissions scandal was just easily measurable.

Everyone likes it that way. Consumers are attracted to features, gimmicks and marketing because that's what works for marketing and sells. No one wants to buy a "900% less accidents than others" car. But everyone wants a bluetooth and wifi enabled car with seat subscriptions. Besides, what's a rational consumer gotta do? They gotta get up at 06:30 and make breakfast for little Timmy and take him to daycare. They need a new car by the end of the month so they better choose between big touch screen or little touch screen with a control knob.

If I can't get a dumb TV, I just don't buy a dumb TV or watch any TV at all. But you can't not travel by car.

You can buy an older car without any screens.
