One of my ideas for a screenplay came from people watching and making up stories about the people I saw. I noticed how now in New Jersey and cities around the Northeast driver use the EZ Pass. EZ Pass allows drivers to attach a device on your windshield and it charges your credit card. No more waiting in line for pay the toll. Even as I write this I am coming up with more ideas. The problem is, is that the EZ Pass could be used to track you too.
Machines taking the place of other machines. People being tracked but devices intended to make life easier. Does this give you any ideas?
