Insurance companies in Britain that monitor how a person drives also keep track of where.

I don't see any harm in monitoring a person's style of driving. However, any system that tracks where people go is a threat to democracy.

The fact that the UK tracks all car travel, through cameras on the street, does not make this new injustice any less grave. Britons must someday demand elimination of massive surveillance; the cameras should be modified so that they don't take notice of most cars, only those being sought for specific valid reasons. The existence of two independent systems for tracking people could be used to argue against any campaign to abolish either one of them.

If we want to end massive surveillance, we must fight against new system of surveillance.

In general, laws should prohibit the operation of systems that collect too much data about people.
