I'll assume the "chaotic steering wheel" is a Freudian slip by your spellcheck and you mean Haptic.
The lack of buttons isn't a problem at all and as you have a 7.5 GTi you'll be familiar with the steering wheel buttons, they may look different but they work the same! It amuses me when people say you have to go through several screens to turn the radio down/change the temperature/etc as they are easily done on the wheel or by voice.
Only had the car for 2 weeks but it once logged me out of my profile, as I was driving along, and I had to re-input my sat nav destination. Other than that nothing, but my car is on relatively recent software (last but one version) and I'm sure things will improve. I actually like the look without buttons to be honest.
