A physical holder for a personal pad device.
The amount of not-invented-here, duplicate functionality that car companies execute poorly, when buyers already have devices that do that well, is ridiculous.
The biggest benefit of aligning manufacturing costs for profit should be jettisoning the "post-sale" revenue streams that drive complicated built-in tech for current cars.
And also, you-know, 100% A+ on getting back to "customize your own car, because it's cheap and supported"!
Owners being afraid of doing what they want with their devices/vehicles has to stop.
