I Believe this is the same for Tesla and other direct to consumer sales in the NJ market. I also wired last year before receiving my Air GT a year ago.
I had the same issue with my model X. I'm 6` and fortunately don't have this issue with my lucid.. or got used it it =). It has to do with the angle of the large windshield and annoying as hell. Aero dynamics is good if you are short.
Just talk to your DA about your concern. However, I would not cancel the order. The car is amazing and which ever build you get I'm sure you will love. I've had mine since April and still love taking random drives in it.
