In the Phoenix area the low temperatures in July, August can be 90 degrees. The battery is supposed to be actively cooled - does this mean that a Tesla parked in a garage will be running its refrigeration cycle 24 hrs a day to maintain a 75 degree or thereabouts temperature? What energy consumption will that entail? Also - if parked outside in the peak daytime temperatures of 120 degrees or more in the sun what will that require just for cooling (of the battery) and also what will it do to battery life? Then there is the need for climate control cooling of the occupants; any expectations of mileage drain for A/C? I've seen lots of issues on the forum due to cold weather but not much regarding very hot weather. I'm on the fence as far as a purchase because of these concerns. Are there any Az owners of the roadster that have experience with any of these issues? I don't think anyone has had one through this last summer. Any info will be appreciated. I'm an early depositer but a late decider.
