It won't be long till they won't just be detecting people, by identifying specifically which people they are. Think of the data! All those cars logging time/location of all those people. (which, of course, will only be used for good and the occasional targeted ad)
Hey Buddy, you realize things improve, right? Especially novel software that has currently improved tremendously in the past 10 years. Are you actually suggesting that it will suddenly stop improving today? Weird.
I think what you're trying to say is cars will start identifying folks and logging their location. Cell tracking/triangulation data is already available from cell companies. Self driving cars aren't going to make things worse.
And visual detection more precise. You can tell not only if someone is usually within a few tens of metres as you can with cellphone data, but exactly where they are, what they're doing, and who/what they're looking at.
