I'm sure the delay with the front mats has to do with design and/or production issues. Weathertech makes them, but I suspect that Tesla has been giving their design input, which could have caused them to go through multiple revisions. Just speculating...My mismatch set has been driving me crazy. Finally I can remedy the situation.
I am baffled why the most useful mats were the last to be released. Like wondering if we're part of a psychological experiment sort of baffled.
