Sometimes some people point to theories that, over time, control/investigation will be introduced to protect people from terrorism and attacks. Of course "for our good".

Already now we are slowly descending towards a surveillance society - conversations, correspondence, (soon bank accounts) - everything is being monitored and
we are slowly getting used to it that it is normal.In China it is even worse: there are already have surveillance program called "Social Credit System"
in place to evaluate the behavior of the population and there will be punishments/awards for your attitude towards the authorities.

The theory that total surveillance / control will be imposed by force is completely wrong - it will be a process spread over time and introduced with
the passivity of the human masses. For example, you will have an implanted chip to the location so you will get to the doctor faster, you will have cheaper tests,
insurance discounts, cheaper holidays, etc… When it will become more popular any goverment could conduct an experiment and let's say mandatory civil
liability insurance for vehicles connected with the monitoring and control system, i.e. the insurer will have a full overview of the route of any vehicle moving
and who is driving it (GPS) and the history of traffic offences + if you decide to install a camera in your vehicle, the discount on civil liability will be
even greater. Of course, it will be completely voluntary, but people who decide to do so will get a discount and so the driver with full monitoring will
get 70-80% discount. It will only be a matter of time before people treat the full monitoring as something normal. The infrastructure is already in place.

- cars full of computers and electronics over which the end user has no control at all
- 100% coverage of the territory with GSM network coverage
- 100% GPS/GLONAS coverage (Russians like to surveillance too)
