Several studies have shown touch screen are less safe. Having tactile controls doesn’t prevent automatic wipers etc, it’s a pure UI choice as your generally run everything through the CAN bus either way.
The initial idea for the CAN bus was simply to save copper by having fewer wires inside the car, it was only much later that touch screens leveraged that system. Basically if you want a truck release from a key fob and a trunk release from a door you might as well have both talk to a computer which only runs connection to the trunk. At which point you can redesign the controls more or less independently because they don’t change how everything is wired up. https://en.wikipedia.org/wiki/CAN_bus
