You want anonymous travel? Drive or ride. Don’t take a cell phone. Don’t take a vehicle equipped with On-Star or its equivalent. Don’t take any toll roads or major bridges or tunnels. Pay for everything with cash. Avoid cities, use rural roads and small towns with no traffic cameras. Then maybe, maybe you can travel anonymously. That would be for the average Joe. If for some reason someone is interested in you, well, then it is going to be even tougher to not be tracked.
Correct.
If you truly want anonymous travel, then invent a time machine and go back at least 50 years.
