The "flagging" that is being done is done by youtube's automated content id matching system. Youtube knows it has many faults so even if your content is flagged, you can deny the flag and continue to gain ad revenue. A more accurate TL;DR would be: "Youtube flagged my video, even though it doesn't, it may lead to me losing ad revenue if the music companies illegally pursue me."

How is Tesla trying to engineer around culture? If anything, they are engineering for our culture that is fascinated with high speed performance cars(Lamborghinis and Ferraris an example) and luxury cars(Bentleys and Lexus an example). Their models are giving what the customer wants. An electric car that is still fashionable in today's taste of cars. Of course the early models will have a few problems, but their widespread popularity after such a limited existence as a car company shows that Tesla is exactly what the consumer wants.
