I think that is a pitfall of specialization and fiefdoms actually. To focus on finer and finer details they must start to disregard or abstract away the other portions because otherwise they aren't specialists by definition. While needed at times it comes with disadvantages of focusing on the 'art' as it were as opposed to the end result and it crops up in all sorts of large projects. The car actually being controllable gets in the way of making it more powerful.
