Regarding that ford advert... I don't think this is a good argument for tesla not advertising. I do NOT think they need to advertise yet, but the time will come.
That ford ad is dreadful, because as is noted, its basically an ad that says "PLEASE BUY ONE, WE WILL BASICALLY TAKE WHATEVER YOU OFFER US" Which is indeed as awful ad...
...but there are a lot of plain FACTS about a tesla that people either do not know, or have actively been lied to about. I never talk to someone about my car who is not surprised by something, such as top speed, acceleration, range, charge times, safety record etc.
Tesla can make ads WHEN they need to, that are informative not manipulative. Some ads *are* a good thing, especially when you have a truly innovative product.
