how is GPS going to differentiate between two trains on a collision course vs. two trains on separate, but neighbouring tracks?

I studied mechanical engineering and your comment explains perfectly why I gravitated towards coding during my univeristy years.

All it takes to produce is time and a macbook and there are no limits to your imagination and creativity.

you forgot a 'yet' somewhere in the last sentence of your comment.

Also consider that an empty battery weighs the same as a charged one. Whereas empty fuel tanks don't.

I wonder how annoying this is for the engineers to stay within landing weight limits (MLW)
