<i>Question: why cannot the "professional" commercial makers do this sort of thing? Why are current car commercials always screaming at me?</i>
Because, when it comes to car commercials, ad agencies are bound by so many rules and regulations regarding depictions of reckless driving and such things that it becomes almost impossible tp create a cool car commercial without running the risk of going to court over it (both the ad agency AND car manufacturer).
These kids are not bound by such ass backwards rules, thanks goodness.
An the car ads that scream at you are from dealerships, not manufacturers. I still remember JOE MYERS FORD (Houston, TX dealership) ad screaming in my ears despite not having seen it in over 10 years.
