       | What a masterpiece of UX/UI. Holyshit.
       | 
       | So many amazing details. Notice how the texture of the trim knob
       | is different than other controls. When cost is no barrier, you
       | can have mechanical switches, toggles, flip-off guards, various
       | shapes and sizes of knobs, levers, color coding, hazard markings,
       | etc. - all made from top notch materials and you bet, the haptics
       | were totally engineered for best possible way to reduce
       | ambiguity. Aesthetics take a back seat.
       | 
       | Also, props to the narrator. She was to the point and well
       | informed.
       | 
       | I hope UI/UX designers (even for web design), industrial
       | designers, architects, ergonomicists, HMI designers be inspired
       | from this with one major take away - stop putting personal taste,
       | aesthetics, decoration, marketing, etc. before functionality and
       | pragmatism. Especially those working in vehicle interior design -
       | people need to realize we drive a deadly 2-ton machine on our
       | roads. Make no mistake, modern regression of UI in cars is
       | because of bean counters - touchscreens are vastly cheaper than
       | physical encoders/switches/toggles, especially automotive grade
       | ones. [1]
       | 
       | Can you imagine if you had to flip a toggle switch to turn
       | bluetooth on in your car? I know you're smiling from just the
       | thought of it. People make the case that UI needs to be simple
       | for people to use at the expense of density, but remember - we
       | already look at the world which is very messy and navigate it
       | without a problem. Millions navigate through airports. People
       | knew how to use Yellow Pages (extreme density) and telephone
       | books. Making UI more understandable is orthogonal to information
       | density.
       | 
       | Unrelated: It is a shame that SpaceX's dragon crew cockpit design
       | ditched all this in favor of a more sexier (arguable) looking
       | sci-fi aesthetics. IMO it looks like a cheap movie set including
       | the space suits.

         | For context, in addition to her career as a fighter pilot and
         | squadron commander, Col. Themely was commander of the 80th
         | Flying Training Wing in 2017 and 2018, which encompassed the
         | Euro-NATO Joint Jet Pilot Training program (ENJJPT),[1] "the
         | world's only multi-nationally manned and managed flying
         | training program chartered to produce combat pilots for
         | NATO".[2] She retired in October 2018.

         | This sounds very smart and serious, which must be why someone
         | makes the same point in literally every discussion of a control

         | have led to an increase in accident rates.
         | 
         | In fact, most modern vehicles use touchscreens to solve the
         | very problem that you are supposedly concerned about. Rather
         | than a complicated cockpit full of individual buttons and
         | switches to control every single function, most modern cars
         | have a few easy-to-find buttons and switches for functions you
         | might want to access while driving (i.e. radio volume, climate
         | temperature, fan speed), and use the touchscreen to hide all
         | the more complicated and lesser-used settings out of the way!
         | 
         | Do you really think that putting your grandmother into a car
         | that resembled that F-15 cockpit would be a safer option? What
         | happens if she forgets where the button is to, say, turn on the
         | A/C compressor? Is she going to read every single label while
         | cruising down the highway at 75 mph?

           | How are either of these things solved by hiding features

           | 
           | Why? Just looking at more stuff makes you nervous? Ever been
           | to a library? Ever cooked a meal? Ever walked outside your
           | house? The world is full of complex "UI". This is a total
           | bullshit minimalism case designers make to satiate their own
           | personal taste.
           | 
           | I would like to see data that proves that "seeing" more stuff
           | impedes the ability to operate something. Hiding stuff is
           | detrimental, I would argue. The hierarchy of menus is equally
           | as complicated as a dashboard of logically laid out
           | "containers", each box decidated to a specific group of
           | functions. It is _exactly_ the same! Your vision system scans
           | through the top level hierachy (Climate Control, Radio,
           | Vehicle Settings, Navigation), then focusing in on individual
           | controls (akin to sub-menu items). The benefits are massive -
           | immediate control, haptics feedback, muscle memory, etc.
           | Negatives a minor and can be addressed - cost, reliability
           | and durability (wearing off labels for example). The problem
           | is - if you look at ALPS catalog of encoders, they are
           | rapidly going _up_ in prices because automotive manufacturers
           | are ditching them and they don 't have enough volume to
           | sustain production and keep costs down. If we had invested in
           | this industry, we would have kept the costs down too. The sad
           | thing is, they are discontinuining a lot of physical
           | controls.

           | 
           | Actually yes. Thank god we have knobs and buttons left for
           | A/C controls. Why didn't hide that in the menus? Apart from a
           | few cars, most cars have physical controls for climate and

             | information. You don't have to hide stuff, you just have to

             | Not UI, but you mentioned one part where software could
             | really shine: instead of getting the feel of the "inverted
             | pendulum" driving in reverse with a trailer, what if I
             | could just turn the wheel where I want to go and let the
             | computer figure out how to keep the back in line without
             | jackknifing on itself.
             | 
             | (I am also sure such software exists, and it fares poorly,
             | otherwise it would be a standard accessory on trucks and
             | everyone would have forgotten how to do it "by ear" by
             | now.)

             | reason that the F-15's interface is this particular way is
             | because cost was not a barrier. While that is part of it, I
             | don't think it's most of it. I pointed out operator
             | training time, which is assumed to be huge.
             | 
             | But there's also a fundamental difference between a fighter
             | pilot and someone driving a car. For a fighter pilot,
             | everything they have to be able to do has to be at a hand's
             | reach in a second. This is an operational requirement for
             | both the "fighter" and "pilot" sides. Driving a car is
             | different; there are many tasks that normal car drivers
             | don't need to do _while driving_. It 's okay for them to do
             | them parked, after fiddling with a bunch of other stuff.
             | 
             | My point: it's not just cost which determines the
             | difference, but training and task requirements.
