Quick poll: who here doesn't want infotainment software in their car? How about keeping cars limited to 1990s level logic: basic ICs, fuel / emissions / safety control (abs, airbags). Something like 1990s Mazda with a japanese-size pickup, miata & basic sedan / hatchback.
Keep the fancy airbags and traction control, adaptive cruise control etc.
Just throw out the garbage custom navigation and radio. It never works well. The display should be simply used for carplay/android auto, and be a black rectangle otherwise.
Maybe sell an addon package to just shove a preconfigured phone into the glove box for people who don't want to tether their device.
