I've already encountered issues with the MG TF regarding the electronics, and the difficulty in fixing things there due to proprietary lock-in (and it's 17 years old). Simply creating a spare key is a nightmare. It makes me wonder what the future of repairability on newer cars with deeply embedded but proprietary software will be like.
I was weary of moving to an electric drive chain and a car I can't maintain myself (my previous Mitsubishi could be serviced with scant more than a 10mm socket and an impact driver) and wasn't sure about losing almost all physical controls -- the only thing that annoys me is there is no easy way to open the glovebox, for everything else the touch screen actually seems easier than my previous physical controls.
