Where is my invasion of privacy survellience?

I just watched a YouTube video on a fight. I am logged into my Google account so Google knows exactly who I am. I post through Google. I have an android phone and I turn on every single invasion of privacy type feature. I have used it for years. I use gmail for my mail account. I search for things on Google all the time. I do that many many times a day for years. Yet to my surprise before watching the video I was shown a commercial for a Mercedes. WTF. I have never bought a new car in my entire life. I only buy used cars. My current car is only eight years old. I always drive my cars until there are end of life. Why am I being shown a commercial for a Mercedes. I can certainly afford one but I would never buy one. Why does Google with all its invasion of privacy opportunities not know this. What kind of crap system do they have. Where is the invasion of privacy that I have been promised. I hope one day to be shown commercials for things that I want. I don't want to see this commercial. It has no effect on me. It is a waste of money for the advertiser. Please Google do a better job of invading my privacy in the future.
