You're using fear words like "terror" as if that should invoke something. I suspect you're confused. Let me re-hash my points so you don't overlook them.
Google is doing nothing overtly strange. The war-driving Google was doing is no different than the war-driving thousands of others are doing. I do it because I find it interesting to see what's out there. Google does it because it wants to map whats out there and use it as another source for geolocation. In both cases, the "personal data" that's being picked up is accidental.
Why do I say your concerns are misplaced? Because, as far as I can tell, you're misguided in to thinking Google is running around logging personal information and feeding it in to their vast data trove. Of course - that's my assumption because, despite your snarky comments on me "ploinking" your points, you haven't made much of an effort yourself at explaining your point and are rather quick to dismiss anything that doesn't fall in line with your general fear-of-Google line.
I should point out to you that war-driving is an ineffective way to gather information. You will, by chance, pick up bits and pieces here and there; an email password, maybe a partial web page, etc. Most of the packet capture is going to be pretty useless. Part of that is due to moving around and altering signal strength. A lot of it is due to the need to hop channels to find access points. If you really wanted to gather data, you would war drive first to identify your target and then sit stationary at a target for an extended period of time to capture traffic. I have seen nothing that indicates that this is what Google was doing.
And so, with further clarification in mind, I repeat... I get your concern for privacy but I find it misplaced. You really should worry more about people like me. Or, worse yet, people with the same basic skillset as me but motivated to do something nefarious with that skillset.
