I just read on fb about a Tesla owner who was warned that he should come on time for his maintenance appointment next week in Hasselt, because otherwise he might have a long wait time because of a massive amount of deliveries. Hasselt is about 2h away from Zeebrugge.
Personally I called the Ghent (less than one hour from Zeebrugge) Sec to make an appointment for my tire swap to summer tires. Much to my surprise, after a long time on hold, somebody from a different sec answered the phone, explaining that Ghent was too busy with delivering Model 3s to pick up the phone, and that she would send a mail so that ghent would call me back. No phone call so far.
so yes, they are in full 'throw everything we ve got' mode to deliver any remaining model 3's
