Yeh that's what I meant. I think it could be one of the X to be tested for safety standards?
You mean one of the mules which was seen a year ago in California, while the picture of it in China is current, right? That also explains the fit and finish. Wonder why they would send a prototype though. The new Xs look way better. Any technical issues to test specific to China? Only thing I could think of is charging, but they could use an S for that, too.
