I have an ID.4 and the worst part about hitting the rear button to roll down the back windows is the delay/sensitivity with the touch sensitive switch. What seems strange about this EX30 design is no directional part of the window switch. You may need to slide your finger forward or backward to open or close the window.
The ID.4 has touch sensitive capacitive buttons on its steering wheel and I personally do not mind the buttons. It is just a new way of controlling your ACC, change songs and volume.
The EX30 is designed for younger people so making the interior more modern makes sense.
