Population needed for technology levels.

The dependencies is what is going to get you for a small population. A small population might be able to make a few automotive engines, but not rubber tires, glass windows, batteries, spark plugs, oil/air filters, axles, break pads, transmissions, etc so therefore, unless they continually retool to make all such items, a car would be impossible.

Of course in t2k much would be recycled, but I am considering new production as that will be the long term goal of any major power. The relics of the past wont last forever and sustainable replacements should be a priority.
