You've hit the nail on the head @realtreebivvy. This is exactly something that has concerned me for some time now. Imagine the increase in revenue and the reduction of enforcement costs that the state would benefit from if we all by carrying our own smart devices (that we pay for ourselves with taxed earnings) are the instruments of our own punishment!

I sometimes turn my phone off or leave it at home when heading away from home. With modern cars it's harder to mask activity but, for that, I have a motorcycle and a vehicle that's not GPS equipped.

Furthermore, the modern vehicles that interact with social media and the like contain all sorts of personal information... and they're internet aware. I'm not happy relying on the ethics and laws at play at the moment in our society so information protection is something that I take on as a personal task where possible.
