The S/X have quite a journey. They will go by rail to Houston. This takes a number of days, then move to a container ship to Rotterdam and then moved throughout Europe plus prep time. I will know in a couple of weeks what ships they will be is my guess. It will likely be more than one ship if we are back to normal volumes. I can track the cars by vin to Rotterdam once the data appears midway across the Atlantic and know the container movements from Fremont to port exit.
I do expect the European production to start now, with deliveries either late August and well into September.
Watch for a hidden vin in your Tesla account and this will be the first clue you have been assigned a car.
