True story, @John Edighoffer was there and can corroborate it: So, while having our little M3OC meetup this evening in Fremont I bumped into a Tesla team member (lot of them come through this particular restaurant) while ordering food. Made some small talk as I questioned him on his particular shirt he was wearing (Model 3 launch team) and what it meant. He would only say "I work on the car". He recognized me from my videos and mentioned the segment I did on the NAVDY HUD. His comment was "won't work" I asked him if he meant "on the Model 3?" He said "yeah" I thought about this for a moment and then said to him "I get it, no ODB2 port on the Model 3" with a smile (the NAVDY requires power from the ODB2 port) as it was the only thing that I thought would prevent it from working. His only response was "you didn't hear it from me" I gave him a pat on the back and said to keep up the good work, we're all counting on them. His parting comment on the way out was "it's going to be awesome" So I take it the car won't have an ODB2 port since it's used for emissions and mechanical diagnostics on ICE cars and I recall Tesla uses their own ethernet type connector in the Model S for this. It was a really interesting evening with a few people who came by to talk. We even had a Tesla line worker on the Model S join us to talk. He didn't have much to say given he's not on the Model 3 team and it's all very hush hush but he did say the line is almost ready to go in a matter of weeks, Tesla is working really hard on it.
