I'm seriously considering "downgrading" to a flip phone with real buttons and no touch screen, despite the absolute ubiquity of touch-driven mobile software - so no, that's a premature narrowing of my words. I disable touchscreens on laptops because 90% of my interaction with them has always been accidental, even ignoring the cases where an overheating panel "touches" itself. Even a touchpad demands a physical toggle, or palm-triggered touches while typing will make using the device an exercise in masochistic self-flagellation. My poor mom is constantly accidentally triggering her's cellphone's touch screen by the slightest brushes of a trailing finger, or simply by holding the edges of the phone.

Put another way: I dispute the existence of touch interfaces - at least for cars - that aren't poorly designed. I will admit the possibility of the existence of touch interfaces for other things that aren't poor, but I'm becoming ever more skeptical of that over time as well.
