A lesson – and a warning – comes in the form of the pending disconnect of the 3G wireless network, which will among other things result in the disconnection of 3G "connected" services millions of car owners paid for when they bought their cars, such as remote engine start/door unlock, roadside assistance/emergency crash response and even GPS (navigation). These wireless features depend on "connectivity" – the ability to send and receive data wirelessly.

When they no longer do, they no longer work.

"We're talking about millions of vehicles that will lose features that were promised to owners, and that no longer will be delivered," said William Wallace of Consumer Reports. "In some cases, those features are safety features, things that can help them from dying or getting seriously injured after a crash."
