There are large implementation differences in touch screens. My wife's care needs several second: turn the radio on, wait for the splash screen, press the drives heat control, wait for it to appear (100s of ms - long enough to notice) then find the button in the miedle of the screen - finally I can change the heated seats. My car that button is always has the button at the bottom of the screen in the same place so is is ms to look and see.
