Because this cover was advertised as being specifically for the Tesla S, I assumed that it would have at least a gap to access the charging port - it doesn't and that's a disappointment and a problem S'pose I have to get the scissors out..! CARSCOVERS REPLIED..... The cover is not designed for use when charging the car. The Tesla should not be charged with a cover on as the front wheels and front grill need to be free to let the charging gasses out. Although the cover is breathable it is still not advised to charge when covered hence no flap. I believe that Tesla themselves will say not to cover the car until it is fully charged.
