Another idea would be to save some space inside, with at least a micro USB connectivity, to allow random devices to be plugged in, inside.
It would encourage the development of such new inboard devices, and would allow users with specific needs to get running. We could add a module with : barometer and/or temperature sensor, sonar, radiation sensor, specific additional light (like so called “black-light” / UV light), parking access radio emitter, redundant microSD slot for raid purpose… just what you need and would fit in.
