Just a remark on the topic. Been working in vehicle software business for 12+ years now and renaming variables is almost never done. In fact I don't remember someone ever renaming a system (global) variable. There tens of thousands such variables in a system, plus about the same number of calibratable constants. We have renamed our drivers variables only when we switched to a newer architecture (multicore ready, AUTOSAR compliant).

The entire code base running a modern car goes well within millions of code lines. Our IDE changed in time from Blue River X32 v5 to internally modified Eclipse plugin. The only major use for us are X32 type contractions. [1]
