I know that the Model S app has been talked about and is still in development. I was thinking that the app is going to be one of the most useful tools for Model S owners. The ability to check on how your Model S charge is coming along from your cell phone while you're having lunch is very cool. Having the ability to cool down your car before you get ready to get back to your car and drive off to your next charge location is very useful. These useful functions of the Model S app are great...that is...if you have connectivity. It might be a good idea for Tesla to install a router in the car to connect your car with your mobile phone so that you can always have connectivity with your car, even when internet or WiFi spots are not available. (Okay, I'll admit....this concept is probably tough for Californians to understand...I bet WiFi covers the whole state!) For those remote locations that do not have WiFi available....connectivity to your car would be nice. So if WiFi is not available...or internet connection is not available, you can at least monitor/control and communicate with your car remotely. The thought of having an in-car router creates some other possibilities like tethering from your Model S. Being able to drive your own mobile WiFi hotspot would be a very cool feature.
