I actually expect that modern cars have an abysmally short lifespan these days due to the way automotive electronics are designed. Mechanically you can maintain a car practically forever as long as spare parts are available (or at worst, they can be machined if the designs are available). The problem is that everything is so intertwined with custom electronics that it probably isn't practical or possible to fix a car with a computer or electronic issue once the manufacturer stops caring to provide spare electronics. And before you say aftermarket, I counter with patents, copyrights and DRM being a legal problem that must be surmounted first.
My personal car right now is a 2005 Cobalt. Its still new enough that I could probably find spare electronics if needed, but in 10 or 15 years? I doubt it even from a dealership. 50 years? Definitely not happening. My wife's new 2017 Ford Escape? I expect this to be completely unrepairable electronically in 20 years, maybe 10 or 15 if Ford decides they don't want to support it anymore.
However, we are veering far from the original discussion at this point.
