GoalNot leave any traces of me using my car.
ResultI did have to cross the toll ring a few times. However, I later discovered that unfortunately my licence plates had been dirty with mud, when doing so. I had also forgot to put my autopass chip in my car (for automatically identifying me as a drive). Despite of this though, Big Brother found out who was driving.
Big Brother sees where and when you drive (and maybe how fast).
What I will do
I will keep driving as before.
Driving past a toll ring is impossible without having a picture taken of your car.
