Tesla never promised that the Model S could turn itself into a hot-spot to share its 3G connection. That is an absolutely silly feature that would cost Tesla a lot of money due to increased 3G bandwidth and which would offer users no useful benefit, but lots of frustration. 3G connections are also not fast enough to support tethering of multiple devices. This is also not a feature that anyone is expecting. If anyone is expecting this feature, it's best to let it go because it's not going to happen. Tesla is not in the business of offering free internet access to owners of its vehicles to be shared among the owners' other connected devices.
