Are you suggesting that your movements are currently allowed to be secret, if corporations or governments so choose? How do you manage that. We know for a fact the government collects and uses that sort of information to harass people (and corporations and nation states). When Google does the same thing to the public we call it an advertising market. This isn't a change from the status quo, it's just opening the information up to the public, for use in promoting the public good, instead of keeping this already-available information secret, shared only among cronies and crooks.
You don't have to like it. You're welcome to do something else. You can opt out. You can even use the public data while you're opting out. But the idea that we want to share data about driving to let our computers drive faster, safer, more efficiently, etc. seems really attractive to me. We all choose to use IP routing and throw packets somewhat haphazardly into the public network. relying on BGP announcements about where we want people to find us. It's public data - It has to be, because it's what the public uses to interact with the system. You're also allowed to set more nuanced boundaries. I certainly intend to demand that the data be shared in a way that's safe for everyone, if they choose to participate. But it's reasonable to imagine that people /want/ that sort of information sharing, even if you don't.
