I think the general consensus of this thread is the following:
1) $30/month for 3G AT&T is too steep and many of us have connectivity issues. Slacker skips, etc.
2) given all the advanced technology in this superbly designed vehicle, if 3G is our only option, this is a step backwards and very disappointing to all of us.
3) however, $30/month would be acceptable if it were 4G LTE instead
4) many of us, including myself, would choose to use our own wifi hotspots instead, on our own plans, and permanently tether the car through our mobile hotspots either wirelessly or wired using the USB and keep the hotspot in the car. This is the most preferred option.
GeorgeB, and/or any other Tesla employee that is reading this, your customers have spoken. please listen to us on this one.
Slight mod to #3 - LTE is only really useful if the browser is useful. Flash/HTML5, etc. Without it, I'm not sure the speed increase matters all that much. 3G at $10/mo is probably better.
