Car companies are planning to collect lots of data about the use of the car, and want to sell it.

The first way a "connected car" spies on the driver is through the connection itself. It uses a cell phone modem, and the phone network tracks its movements just as it tracks a cell phone.

You can disconnect the modem in your car, probably just by unscrewing it. Then the phone network can't track you, and the car isn't connected, so it can't send any data about you, such as where you travel or what you say in the car.

But it might save up data to be sent or extracted later. To prevent this, we need laws.
