What the designers/engineers want (convenience, ease of use) is often sidelined in favor of making money (keeping mfg costs low, dealing with supply chain issues)
Our heat-pump water heater is outdoors, so it doesn't cool the house down any further. Our hot water cylinder is also able to heat water if the heat pump can't keep up.
My chevy bolt is a nice mix I find. It has physical buttons for: climate controls, cruise control, media volume, media channel, lane keep assist, sport mode, gear selection, park brake. There are also voice commands, which I use for selecting navigation destinations.
Touchscreen for other things: android auto, apple car play (which provide maps) and more complicated user settings (such as whether you want the lights to stay on after you turn off the car for a while)
Is it not possible for an individual engineer within Ford to have some creativity? To hack on something they weren't supposed to? Not every output from a company is top-down, corporate-overload, profit maximizing.
Do you really think this was originally a planned feature by Tesla? That some cynical marketing manager sat down ans though "if we do this we'll get X impressions leading to Y new sales, lets allocate 0.7FTE engineers to the task"?
I very much doubt the design requirement for the Model X include a specification for "muat be able to produce Christmas shows". This sure looks like some engineer had a spurt of creativity, which qualifies to "hacking" to me.
