I think that's an excellent point. I suspect (and veen and I have discussed at length) that google is most likely to hit up auto manufacturers for licensing, which further complicates the issue. That's why I called it "googlism" instead of any specific product - if it were my business, I'd obfuscate liability with every move I made.

So the way this typically works in the land of liability disclaimers is

(1) I make you fill out a document whereby you foreswear any opportunity to hold me responsible for anything for any reason ever anywhere.

(2) I do something that kills you or almost kills you.

(3) You sue me anyway because it's not actually legal to sign away your life and any contract that overshoots the standards of reasonable risk generally gets invalidated the minute it rubs up against statute.

So it kind of boils down to the same thing - yeah, you can throw disclaimers at the problem til the sun goes out but you reach the point where a judge and/or jury says "Google can't make a service that will voluntarily, willfully injure its contractees regardless of how many degrees removed they are.
