Lou, it's because of dumbasses. Case in point: This feature would have saved the gate at our transmitter site when my former boss hopped out of the vehicle to punch in the gate code without putting the vehicle in park.
I eventually had to tell him that there was no way on God's green Earth that I would ever ride with him again, even if it were to take me to the emergency room.
Yes there will always be dumbasses but make the operation of basic controls INTUITIVE, so they can be operated by feel and make them the SAME, from one vehicle to the next.
The term "standard shift" in reference to a manual transmission comes from this concept.
At one time not all auto trans shifters used PRNDL, some had R at the extreme right next to L, this caused accidents when a person switched from one make to another.
If you make controls simple, and intuitive, even dumb asses can drive, as I saw when I started driving in the early 70s.
Tech does NOT make everything better, it is effectively proven. We have to have more tech to make up for the initial un-corrected mistakes in tech!
Human factors engineering, auto manufacturers don't pay attention to it.
