I can't understand the meaning of this sentence. What does this sentence mean?
McLuhan had a notion that North Americans go out to be alone. And he once shared this feeling to Henry Ford II, but Henry seemed apparently incurious about it. But later McLuhan discovered that his idea was used by Ford Motor Company without giving him any credit whatsoever. Based on his idea that company made an advertisement and started running it on television. That advertisement showed a man leaving a house which was full of people screaming at one another. The man got into his car, rolled up the windows, and putting on an ineffable contentment on his face drove off.
What I think this sentence means -
North Americans seek to be alone while going out.
