Can't answer where they came up with that number but it does seem rather larger. The only comparable machine where we do know the number is the Mars Curiosity Rover running somewhere around 2.5 Million LoC. Now, given that there are upwards of 200 micro controllers in a luxury car, I can see that number growing exponentially, but 100 Million???

2.5 MLoC sounds extremely high even for a Mars Rover. I really wonder how it's counted? Is it C code or ASM instructions? Does it include all standard libraries that get referenced, even if they end up not being compiled into the final binary? Or is everything just written in Java and configured with XML?

Highly doubtful, Opportunity is at 4,000+ days of uptime...

Embedded Windows in the UI (if present) would probably account for a large fraction of those.

Yes, that has always been my assumption -- they're probably counting operating system, libraries, etc. in those mlocs. It's X MLOCs in the car, not X MLOCs written by the car manufacturer.
