I notice that in a Model S the Wifi is turned off (or at least, disconnected) when the car is in Drive.
Why is this?
Some have mentioned that this could be because the car is assumed to be (about to) be moving and assumed that the WiFi is a static location.
This assumes all sorts of things about how the WiFi network is provided (all sorts of details the car cannot know). The assumptions made are also quickly going "out of date" in terms of how TCP is provided. The growing number of mobile HotSpot options for WiFi being just one such change.
Also: this assumption means that I cannot use features of the car if the Tesla-provided (via 3rd party) networking goes down (as it did in the UK very recently).
For me personally: I get way better data networking on my hostpot for the areas in which my car is most of the time then the lcoal GSM on the car does.
Also: if/when the hardware in the car for GSM fails or needs to be replaced ***or becomes obsolete*** will I be required to replace/upgrade the hardware in my car in order to return it to proper function (eg: mapping, some security features, GSM-based suspension settings and much more).
Could we have an option to just leave the WiFI *on* when driving?
