"Product placement" usually means the form of stealth advertising where a car company
pays a major show or a blockbuster movie to put their cars on display. Such as the E-Tron displayed in the recent "Avengers: End Game" probably cost Audi a couple of million dollars.
Which is probably more than the profit they'll ever earn from E-Tron sales, they need to earn more than 2 billion euros, around 600,000 units for a break-even:
I don't think Tesla is paying for displaying Teslas in movies or TV shows.
BTW., funniest ever product placement I saw was in the first "Jurassic Park" movie: there's at least 3 edited versions of the movie that are advertising the hardware and the OS used to control the theme park: "Silicon Graphics, Unix", "Thinking Machines, Unix" and "Microsoft, Windows NT" were all variants I've seen/heard, post-edited into the movie, as if it was an excited, authentic statement of one of the major movie characters, with the exact words depending on geographic region.

(The true system used was probably Silicon Graphics/Irix, the rendering system du jour.)
