When I took it to the service center, it was a Saturday. This was after opening a ticket, opening a ticket with "executive escalate," and talking to the Raleigh sales office who said they'd look into it. After about an hour, they told me it had to be taken care of by an engineer in California and he didn't work weekends. "Maybe Monday." Thursday I get an email from Utah apologizing for the delay and wanting to know if I still had the problem. It had updated overnight and took 16 days.
I had all the relatives in town for Christmas and was showing off the car, even with the expired temp tag. Just couldn't show them the autopilot. We're on Day 19 of the expired tag. I have this vision of an intern still sitting in line at DMV with a briefcase overstuffed with paper forms.
Start early, the problem doesn't fix itself.
