Right, but only the tin foil hat crowd are placing their cell phones in aluminum foil bags or pulling their sim cards and batteries.
The reality is most of the people "concerned" about EasyPass Transponder data are willingly giving up much more data via their cell phone (not just driving locations, but walking locations, final destinations, dwell times there, etc. -- read the article!). And while they "worry" about the big bad transponder, they continue using their phone, navigating with Google Maps, playing Spotify over their car audio, checking a Yelp review, and probably texting. And big, nearly invisible private corporations are collecting all their location data (and ancillary phone use practices) to sell to the highest bidder. It is not even the government you need to worry about, it is the corporate oligarchy.
