I imagine it would feel like Tesla has screwed those that have waited longer than they were told.
Which is many of us who ordered in Feb. I am now beyond the end of the date range I was given when I placed the order. I placed my order the day after it was lengthened, so those with unfilled orders who placed them a few days before me are well beyond what the were originally told.
Nothing we can do about it, but yes it does come with a touch of 'feeling screwed'
