They won't give you a factory tour but if you ask Naomi nicely, as a reservation holder, if they have a 'test drive' slot available somewhere (e.g. Santana Row) yes you can probably have a 15-20 minute test drive.
Suggest you email her ASAP because when I did this there was quite a leadtime / backlog of people wanting test drives and (at least at that point) very few cars available for test drive.
This was September last year.
Around Santana Row is good, you get a few runs on different types of roads, a few sweeping freeway entrance ways, a couple of straights onto the freeway and then opportunity to 'test' the epic instantaneous acceleration of 65mph-85mph testing how you may want to do overtaking maneuvers on the freeway.
You won't want to give the car back.
Make sure you're comfortable driving there, you do sign quite a disclaimer to have a test drive.
