5. Backup cameras. They're legally required in some jurisdictions (so I heard), and genuinely contribute to safety, but they require a screen. Once the screen is there, there's both less space for buttons and a virtual hook for features.

I've seen the backup camera integrated into the rearview mirror in some vehicles. That doesn't have either of those drawbacks.

All cool until there's a wall or something like that starting right at the height of the roof. Can't see it in the camera but can in the mirror. Most cars with rear view cameras even warn: don't reverse by relying on camera only.

I have been surprised to learn that regulations only require that the backup camera turn on when you go into reverse; not that it stay on while you are in reverse. Some cars let you navigate away from the backup view even while moving backward.

There is so much opportunity for better regulation, without making more numerous regulations.

Are you telling me you don't need to find the exact right backing up tune?

You can just use the screen for infotainment and satnav though.

I already have a screen showing what radio station is playing, and one on the dash telling me where to go. If a screen is required for a backup camera, just combine it. If I'm reversing I probably don't need the satnav anyway, whereas if I'm reversing or using satnav I probably do need other functions which just means you need an even bigger screen so you can fit everything on.

[emiliobumachar]

You're absolutely right, but my point is that the minimum number of screens is no longer zero.

[bluGill]

Sure, but the screen need not have any touch capabilities. It doesn't need to be large either. A 2 inch screen is large enough for the camera functions.

These days the instrument cluster is being displayed with an lcd. It could be used for the backup camera and wouldn’t be practical to be a touchscreen.

in addition, my Volvo does a "360" view, which is pretty darn useful for parking.

My Nissan Qashqai has it too. I absolutely love that 360 view and will never buy another car without it. It makes parking sooo much easier.
