As someone who has only been driving for a couple of years, please don’t make my UI as complicated as my car's 'interface'! I take your point about 'portability' (although different cars are notoriously different to drive - even the gear pattern on the stick varies between different manufacturers) but the initial learning curve is incredibly steep. If I really wanted to, I could learn emacs from a manual. I can’t imagine learning to drive without another human involved.
