Yeah I really hope other car makers follow because I fucking hate touch controls in cars with a burning passion. It's idiotic and not safe at all.
Same goes for kitchens. Give me real buttons and knobs and not these abhorrent touch panels that refuse to work every third time. A good quality kitchen appliance is identified by high quality knobs that last for decades.
In general high quality things tend to have physical buttons and knobs as opposed to touch screen devices.
Instead of turning into e-waste after 5 years or less they can last for the next 30 to 50 years.
How many smart thermostats have become obsolete because their service providers stopped providing cloud services for them?
I just tore apart a working thermostat that almost 80 years old now (to understand how it works) and in perfectly working condition. It uses the physical properties of the materials inside to measure temperature (a coil of metal expands and contracts causing a pendulum to move clockwise or counterclockwise). Suspended at the top of this pendulum is a small vial of mercury containing two electrodes. When the pendulum is far enough counterclockwise the Mercury slides in the vial and bridges the electrodes, turning the furnace on, when the pendulum is far enough clockwise the mercury slides to the right and no longer bridges the electrodes.
When you set the temperature on the thermostat you are changing the default position of this pendulum. Meaning that it has to move more or less distance for the bead of mercury to bridge the circuit.
It's brilliantly simple and will continue to work essentially forever. The physical characteristics of the materials involved won't change.
You should read Exhalation by Ted Chaing if you haven't already. It's a quick read
