To clarify on Google Car http://en.wikipedia.org/wiki/Google_driverless_car says that Sebastian Thrun was leading Stanford lab for the DARPA challenges few years ago. So yes Google does have a driverless car but as far as I can most if not all of the work regarding the actual driving was done before it was related to Google. Now regarding Google Maps and Street View it is probably mostly internal research but I don't think it can be considered related to driving. It is mostly indexing and searching (which is Google core business).

Regarding war and my doubts on peace, US DoD as #1 world employer http://en.wikipedia.org/wiki/List_of_largest_employers and China trailing behind.
