My wife recently had the chance to use 3 different car UIs. Our own little Hyundai Elantra GT 2013. No touch screen. Connect Android phone via bluetooth. Run Android Auto app. Navigate, stream music, etc etc. We're both used to this, so it's very ingrained/easy to use the phone's touchscreen to navigate the UI. Mercedes C300. Big screen, but not a touch screen. You had to twist a joystick then move it up/down/left/right depending on... something. That UI control mechanism did not work well with Android Auto, since there were different "sections" to each screen. You had to figure out via trial and error which joystick control method to use to switch sections. Plus sometimes moving the joystick would twist it, thus ruining whatever UI navigation you were trying to perform. Hyundai Sonata 2019. Big touch screen. Worked perfectly with Android Auto. Not one single "mis-click" like with the Mercedes.
