They already have instituted more tracking methodologies over the last 10 years. They had an entire data mining effort for years. They've been setting up more and more data demands for air travelers. They've demanded more people get, and use, passports that now contain biometeric information. They have been approaching libraries for records of materials checked out. They tested a face recognition system at a Superbowl. They have been looking at importing the persistent survellance technology developed for Iraq back here to the US for domestic monitoring. They are working right now on procedures for extensive use of unmanned drones for domestic monitoring.

It isn't an extreme extrapolation to presume that they would be interested in using monitoring technology on the nations highways to attempt to detect travel patterns. Heck, some folks might consider it malfeasance if they DIDN'T.
