That would be the absolute dream engineering brief. If I actually sit down and design that vehicle, it would have something like this. List, off the top of my head.
1. You keep the modern metallurgy and the crumple zones. You keep ABS and basic traction control because they are solved problems that save lives without needing cloud connectivity.
2. Instead of a 2000 USD proprietary touchscreen that will be obsolete in 3 years, the dashboard could be just a double DIN slot and a heavy-duty, universal tablet mount with a 100W USB-C PD port. The car provides the power and the speakers and my phone provides the maps and music. When the tech improves, you upgrade your phone, not your dashboard.
3. Nobs and buttons instead of touchscreens like VW has done recently, if my memory serves me right.
The tragedy is that regulations in the EU and North America make this incredibly difficult to sell. The sane environmental stuff you mentioned has morphed into a requirement for deeply integrated electronic oversight. But I genuinely believe there is a massive, silent majority of drivers waiting for a car that promises nothing other than to start every morning and never ask for a software update.
