I have mentioned more than once my dislike of modern automotive design, specifically when it comes to things like the multifunction touchscreen displays in almost every new vehicle over the past few years. Functions that used to be controlled by switches, buttons, knobs, and sliders have migrated over to the LCD touchscreens that take up a portion of the dash, mostly in the center. Some have gone so far as to replace the gauges – the speedometer, tachometer, fuel gauge, temperature gauge, oil pressure gauge, battery voltage, odometer, trip meter, and so on.
Is it that I am an “old faht” that doesn’t like all the new doodads and gizmos that has me writing this? Considering that I am a techie and have been one since the 1970’s, it isn’t that at all. It all comes down to the fact that some user interfaces, in this case for motor vehicles, really don’t lend themselves to LCDs and touchscreens. The newer technology, while really cool and cool looking, has one major downside to them:
The driver has to take their eyes off the road in order to use them.
It appears the UI/UX (User Interface/User Experience) designers, also know as “Buttons And Stuff Engineers”, have forgotten that distracted driving is a Bad ThingTM. Any time a driver has to take their eyes off the road means they aren’t paying attention to their driving which in turn can lead to accidents. If they have to take their eyes off the road to handle functions that used to be controlled by physical controls, the aforementioned switches, buttons, knobs, and sliders, they are driving distracted. Drivers could control many functions without having to take their eyes off the road because muscle memory let them do so without having to look at them. The fan speed control, temperature setting, and vent controls were always in the same place. The same for headlights, windshield wipers, radio volume, radio station selection, and so on. But with the new LCD touchscreens muscle memory doesn’t work.
That could be why automakers are reversing course, at least partially, bringing back those switches, buttons, knobs, and sliders that control common functions used every day by motorists, even if it is the onboard vehicle control modules that still drive those functions. They have come to understand why their customers detest using touchscreens for these functions.
This begs the question “Why did automakers switch over to using touchscreens?” The answer is simple.
Costs. Touchscreens are cheap.
They can control numerous functions from a single interface depending upon the programming and the design of the systems in the vehicle. A single data connection to a vehicles control module(s) can control all of the usual functions. There’s no need for separate wires or cables for each of those switches, buttons, knobs, and sliders. And while those touchscreen interfaces are cheap, replacing them is not. You know the dealerships and repair shops will charge a fortune for a replacement. All told, the cost of that touchscreen interface including its associated electronics is probably less than $100. But they’ll hit you for up ten times that much plus labor if it ever needs to be replaced.
And there’s also this: If the touchscreen fails your vehicle just became very dumb. You won’t be able to use any of the functions it controls. Sounds like fun, doesn’t it?
Now about the crappy engines the automakers have been putting in their new vehicles...
