Elon Musk is the master of reverse psychology.

The video leverages the high-profile nature of Elon Musk and a counter-intuitive, candid response to a common investment question, which creates intrigue and engagement.

A video clip shows an audience member asking Elon Musk why they should invest in Tesla over Mercedes Benz. Musk responds by explaining that he rarely encourages people to invest in Tesla and has even warned that the stock price is too high.

Tesla (a car manufacturer and energy company) — it is the subject of the investment question asked by the audience member and discussed by Elon Musk. Removing it would change the entire topic of the video. Mercedes Benz (a car manufacturer) — it appears as a comparison point in the audience member's question. Removing it would change the context of the question but not the core subject.
