Don't think of it as 'those near the factory get theirs first', but rather, 'the first cars delivered will be to those near the factory.'
Any shakedown cruise issues will be long over after a few thousands cars. Once they are ramped up, they need to deliver equally to all areas to avoid truck scheduling problems.
Ordering on 4/19 means you are about 380,000th on the list.
Thank you kindly.
