>Tesla already doesn't run ads

That is a great idea, running ads in Tesla cars. They can introduce a monthly subscription to opt out of the ads.

Now that the words have been uttered its become inevitable

I thought that was already obvious when Google started working on cars ;-)

All he has to do is tweet something about Tesla... instant advertising.

He tweeted all sorts of ridiculous nonsense, to include talking about Tesla, long before he bought twitter

Well, he could already do that.
