Look, I fully understand the value of audio. I know you are just trying to provide constructive criticism but.. a) I'm not the owner of the channel, I just contribute. The owner will never see your comments. b) Shooting unscripted and ad hoc in a difficult environment is a massive challenge. You do the best you can. If you watch other videos on that channel you'll see that in a controlled environment more care is taken with the audio. c) In the rapid world of YouTube getting the content out far outweighs scrutinizing every edit point. No one is getting paid here, it's just a hobby.
Life is short, enjoy the amateur videos for what they are.
Heidenau tires have actually been feature on the channel. So yes, they are here.
