Exactly! Like, take a basic car, and make it an EV. It doesn’t need to be a spaceship. I just need speed, charge level, maybe a tach or electrical load indicator, and a range estimator, all of which already exist on a basic car’s dash. The head unit can remain a separate device that connects to my phone for navigation and phone. That’s it.
