I don't own this space under my name. I should have leased it while I still could

You mean like the internet? Which is broadly compatible but treated differently in a multitude of platforms.

Or radios? Provided the all use the same transmission protocol - AM, FM, digital and have sufficient channel separation or bandwidth.

Or ATC? With huge human interaction.

There are countless systems that work seamlessly across international borders - all it takes is some smart people to agree to a basic framework. For instance military Link systems. The major problem there is system upgraded developed by a wealthy country which creates major improvements at a cost that can not be afforded by a poor country.

That is one of the some of the issues to be solved. But progress will be extremely slow and cautious. One solution, as in aircraft, is zoned in which only compliant vehicles are permitted.

I will just end with two examples of global incompatibility 110v/220v AC or DC and LHD/RHD.
