Regarding the updated headlights. The dude in
this video did a "drive off the lot video" and shows off the new console
and makes a brief reference to receiving the new headlights. And, look, I'm not a huge YouTube watcher but I've allowed myself to settle into the warm embrace of other people showing off features of their own Model Y. Do I watch YouTube more than my 12-year old now? Maybe. Do I care? I do not. I deserve it.
At any rate, this guy references the fact that he has the new headlights (around the 4:28 mark) and it's not an MYP. He does a walk around the vehicle and the wheels are 20" and not the 21" on the MYP. Unfortunately, he doesn't linger on the headlights so you don't get a great view.
I can't verify that he's correct but he also mentions that this is his 4th Tesla so I'm assuming that he pays attention to such things.
