I recently placed an order for a Model S and expecting delivery in a few months. I'm planning on parking the car outside in front of the garage and having the Wall Connector on the inside. Is there any issues with garage door openers and that cable running under? I want to avoid having to leave an opening. I'm also considering the UMC NEMA 14-50 setup as I believe there are no problems with that but I'm not sure if winter pre-heating will cause range loss when only 32A is given (since cabin + pack heater can take up to 12KW). The NEMA 14-50 wouldn't qualify for installation incentives from what I see either, I would have the Wall Connector setup for 40A which is a bit better. Looking forward to your ideas.
