Well its very obvious our brains work very differently then, I do have a touchscreen in my current car, luckily nothing critical is controlled from it as it is a pain in the ass to operate on less than perfect roads, (not helped by moderately sporty suspension), which is probably why Honda provided a little 4 way joystick below it.
The thing with tactile controls is you don't need to see them. I certainly don't look at the gearstick, handbrake, indicator stalk or headlight stalk to operate any of them, not after the first couple of days (if that) of driving a car. Adjusting the aircon temp or fan speed in my car requires looking, as there is no adequate tactile feedback from the temp buttons or the touchscreen that you have found the right spot, the temp up and down button are side by side and not dimpled in any way so without looking I can't reliably be sure which one i'm hitting, even after owning the car for nearly 4 years.
Without the tactile feedback it is very hard to learn where exactly it is relation to your seating position. Your brain learns approximate positions then does final guidance based on tactile feedback. Your little finger touches the wiper stalk first, your brain knows your hand is high and adjusts trajectory down ward so you end up in the right place. Your index finger touches a flat bit of glass an inch too high.. no useful feedback as that bit of glass feels just like the other bit.
It would be quite interesting to conduct an experiment in a car like mine, sit the regular driver in the car and blindfold them and randomly give them instructions to turn the volume knob up or down and touch the icon on the touchscreen they use most often.. i would bet their success rate on the volume knob is >95%, but they miss a similarly sized icon on the touch screen at least 40% of the time.
