Last month, when the pop-up appeared on the Model 3 page regarding the commencement of test drives by year-end, I clicked on the button to schedule one. However, the resulting page only listed the Model S and X for test drives, so I bailed out. Nonetheless, a few days later, I received an e-mail from a Fremont-based "inside sales advisor" inquiring about my interest in test driving an S or X. I replied that I was only interested in the Model 3. He wrote back that, "test drives are estimated to begin towards the later end of this year." As someone based centrally at the factory, I assume he has more direct access to official facts than the average store employee. Of course, this all transpired a week or so before Sunday's tweets, so things could have changed since then.
