This would be a mistake (and this is not the first time this discussion has happened). Zero is a tiny company of maybe 150 people and can't support the R&D, component cost, software cost, and update cost of this yet.
Everyone wants a Tesla screen, but that screen and what goes behind it takes a small army of people to make work affordably at scale.
They should focus on making the phone app richer and easier to work with, because phones update faster than motorcycles or cars, and because a richer data and control link would be all they need to maintain.
Honestly, what's really ironic about this is that the size of the Zero means that you can't even see the display while riding if you're looking straight ahead, so what's the point of a richer screen right now? Zero needs a "full cockpit layout" where the rider can see the screen properly before updating the screen.
