Unless Elon lends out his Vin #1 X to these outlets for longer drives and testing (as he did with his Vin #2 S three years ago), it may be a while before we see more elaborate reports.
Strangely, there's no mention yet of "Get Amped"-style test drive events for customers for the X as they did in many cities for the S in the fall of 2012. They are seemingly expecting/hoping for the Sig and early General Production res holders to confirm without a test drive.
