When you drive, your goals and the goals of everyone else on the road are roughly aligned insofar as you all want to travel from one place to another place quickly and safely. There are pretty rough consequences for those whose goals aren't similarly aligned. So yes, you could be killed by someone else driving drunk, but it's relatively unlikely.

Google's goals and mine aren't aligned at all, except instrumentally. So Google cares about my privacy up to and until it costs them less to not care than to care.

I'm fully in the Google camp, but let's be honest about the fact that we've made a deal with some supernatural being. We just hope it turns out not to be the devil.
