Replacing Carburetors with electronic injection [of many flavors] was the best electronic vehicle step forward of all time.
Putting a Hot Spot in your dash? Questionable, as one can do that other ways without integrating it with one’s vehicle wiring and paying over and over to do it with multiple vehicles.
I don’t know about that stuff. But I would like it if they still made a car with mechanical doors, windows, and not all of the fancy gizmos that we pay for now.
Some people want and perhaps need all of the ‘new stuff’. But some of us just want to drive to the nearby grocery or pharmacy a few times per week. All of the electronics just add to the chances of something going wrong - and big $$$ to repair.
My first new car was the cheapest car made in America at the time, a little Chevrolet hatchback, perfect for all of my purposes. It lasted me 10 years with only about $1K in repairs over that time. When it ‘died’, I gave it to my Bolivian immigrant neighbor who figured out how to fix it, and his wife drove it for a couple more years.
