It would need to be in exchange for free premium connectivity or something.As a stockholder who wants to become rich, I wouldn't mind ads going into the cars if it brings in significant revenue.
As a Tesla enthusiast, driver, and....stockholder....I would HATE ads going into cars. I don't think Tesla will go this route. I also pray Tesla doesn't go this route. Not worth the money. Who wants to click to close ads in their car? It's annoying enough in the Solitaire game on my iPhone.
Amazon does this with Kindles. You can pay say $100 and have no ads, or spend $75 and your Kindle has the occasional ad.
