Yes, it is a mess. At over 15.000 pages, AUTOSAR specifies not general utilities, libraries, battle tested data structures used in the automotive field or whatnot, but actual automotive components that in theory can be developed independently and combined to build the whole car. XML being the medium of choice for this standardization doesn't help either. You're left with tools upon tools that modify XML files and generate C code based on those files and very little opportunity to actually look/modify those C files by hand, even in trivial circumstances. In short, the AUTOSAR idea, from what I've experienced, is to hire an army of mouse-clickers that can use shiny tools to assemble and configure every aspect of the car. They would not learn C or any programming, but learn the actual standard and know what you need to click or check in each and every instance. The tools would then take care of bringing in the code and generate the header configuration files for you.

Anyway, not mentioning AUTOSAR might be a sign that its days are numbered, perhaps?
