This is more of what I was getting at regarding customization and the watch analogy upthread. Even with additional data on the screen I would think you just want secondary information that you can glance at and easily find, such as moving the odometer from a swipe to just a smaller space on the main screen. I'd also like to have all the battery/range info in one spot. For other stuff, I'd be okay with a cloud or rain icon, but not like, stocks or news headlines
Fwiw the speed indicator feels oddly sized to me. It's the biggest thing on there but not demandingly huge, it's dependent upon the negative space for your eyes' attention. TBH I don't look at it much though with speed up on the HUD.
