As substitute for physical state inputs I could accept separate inputs for different states (this excludes off/on toggle buttons, but could be satisfied e.g. by separate off and on buttons) and a state indicator in a visible location, preferably close to the input.
Power windows are close to fulfilling this (up/down separated, and it might be argued that the state is sufficiently obvious, though questionable for the rear windows). A central lock controlled through a common lock/unlock button does not satisfy this.
Hard to read in direct sunlight, too. (Partially-)Reflective displays with perfect dailight readability exist (used in aircraft), but they would likely not satisfy the cheaper-than-buttons requirement.
But cars without roofs are getting out of fashion anyway. Next step after no steering-wheel will be no windows.
More generally: I want to be able to feel the state something is in. Whether it is push/pull, turn, or flip doesn't matter, but it has to physically maintain the state I put it in.
An exception to this of course are functions that are used temporarily, like the horn, and the wipers swipe-once. And if direction indicators turn off automatically, the input device has to change its state accordingly.
On www.a.com players build dungeons that are attacked by AI. On www.b.com players attack AI generated dungeons.
What neither players of a nor b know is that they are playing against eachother. But both are amazed by the AI. And there's none of the drama usually involved in anything pvp.
