The thing is . . . it's not actually an OTA update.
@Jackles found this under the 'keys" paragraph of the update notes:
“To ensure the highest level of security, part of this update requires a quick in-person service by a certified Lucid technician. This process is brief, complimentary, and can be completed at any Lucid Service Center.”
This would suggest even mobile techs can't do this, so I wonder what this means for those who don't live near Service Centers? Will Lucid transport the cars? Do owners have to get there on their own?
