With the addition of using a hot spot while driving, what service will be unavailable if I do not register to the premium connectivity package and simply connect the car to my phone hot spot?
I believe the car will see the hot spot as it would any other WiFi access such as a home wireless network. You could probably watch entertainment and surf the web. I think if anything the traffic info may not be available. I think the streaming music also may not be available as there are license fees involved that are part of that $10.00 per month.
Satellite view maps and traffic visualisation are the only two things you would gain by paying for premium connectivity instead of using a WiFi hotspot. All other services (including streaming audio) are available.
Connectivity is an important part of all Tesla vehicles, further enhancing the driving experience by providing access to features that require data usage. Find out more about Standard and Premium Connectivity.
