The Ford Motor Company is letting owners turn their cars into mobile broadband hotspots from next year with the newest version of its SYNC in-car connectivity system. Sadly it's currently only available in the USA.
Customers will be able to plug a standard USB Broadband modem into the SYNC system's USB port. This creates a WiFi service within and around the vehicle, enabling passengers with WiFi-enabled laptops or mobile phones to connect. The SYNC WiFi system uses WPA2 security, requiring users to enter a password before they can connect to the internet. In addition, the driver must authorise each device when it first attempts to connect.
