Same here.
Alternatively, press to see if your car carries the upgraded fuse. Might be a backdoor way to quasi-confirm the upgrade without actually upgrading.
If the SCs won't confirm eligibility for the upgrade nor the upgraded fuse for your car, you can always wait for the next natural disaster, drive into the storm, hope Tesla opts for the temporary courtesy unlock, don't die, make it to a non-destroyed SC, request the uncorking, hope your eligible, get it uncorked, and then bank on Tesla not downgrade it when the courtsey unlock expires. If that works, you'll have a truly unique car: Performance S60D!
