After 27,000 miles in 1 1/2 years, during which time I have been out of the US more than in it I have learned quite a bit about my car. Among the things I learned, important to only a few of us, is that one can leave a Tesla plugged in for months while the car waits patiently for the owners return. Tesla even told me there was no problem at all, just leave it plugged in set fro 50% or so. Thanks to a Norwegian post about leaving a Model S outside in the winter for a month without being plugged in I gained confidence so I took delivery on mine several months before I had my own charging. My Model S lost about one percent per day, so I charged to 90% and left it for as much as two months. Zero problems ensued. Now my car has 27,000 miles and still zero problems. An ICE has invariably issues with fuel pumps, water pumps and myriad other fluids and rotating pieces that really do not like to sit for months on end. I have lived in more than one country at the same time for thirty years and have always had one or more cars in each country, resulting in them sitting for months without use, followed by intensive use for a while, then sitting again. Early on I learned to use trickle charger for batteries, but one thing that always followed was early failure of all those parts I mentioned. Some manufacturers dealt with issues under warranty (Fiat, Peugeot, Maserati, Porsche, Audi) while others repeatedly denied warranty repair (e.g. Alfa, BMW( three cars, three countries, no more BMW for me!). I have posted this in the Technical forum because it does not seem to fit easily anywhere else. Still, Tesla is the ideal vehicle for people with multiple residences and/or heavy travel schedules.
