Of course knob cost more than a touchscreen. They are more expensive to produce, since you have more parts, more wiring, more steps to assemble it. Like it's more expensive to produce "analog" electronics than putting a microcontroller and do things in software. The question is, what is better? To me touch interfaces in cars are very bad from a safety standpoint: they are impossible to use without looking at them, thus not looking at the road. Physical buttons are more practical, since you can just feel them, I don't need to look at my AC controls to change temperature, I just have to rotate som knobs or push some buttons that I know where they are located. Same thing with radio controls, I know where the buttons are and I can perfectly operate them without looking at the radio itself. Beside that, but it's my opinion, touchscreen are more ugly to see, all modern car seems to have a big tablet, that not only is ugly but it reduces the field of view of the driver, or of the passengers. When I'm on a car trip I want to view outside the panorama, not an ugly 10" display to show me the radio station that I'm tuned to as it did the old 20 character display of my old radio. I love the dashboards of older cars, with knobs, switches, dials, colored LEDs, an 8 segment displays. Now every car seems identical to another. If we talk about more data presentation, yes more useless data presentation for sure. Useless information distracts you from driving, and thus makes car less safe. If you want then to extract whatever other data from the car... a cheap ODB-II interface that connects via bluetooh to your car is all you need. Of course to be used only when you are not driving. |
