Think the point is, we all speed from time to time, when conditions allow.
The big point is we do not film it, then we do not upload it to the internet for the public to see.
I think he is playing a very dangerous game, especially considering that so many people who don't have much better to do have no doubt reported his videos to the police, so I am sure the police are aware and are no doubt collection evidence to make a prosecution, they are probably just biding their time to really set an example that will send a big message.
He is either very brace, very stupid or thinks he will not get caught, but to upload videos that blatantly show racing on UK roads, thinking people are dumb enough to believe its in Germany when its clearly UK, or that maxing out 3rd or even 4th gear in a powerful sport/GT car is under 70mph is just bonkers.
I will be personally amazed if the police don't go knocking on his door at somepoint, if I was him he should calm it down, pull some of the blatant speeding/racing videos down and continue what he is doing as some of his videos are good watches, you don't need to break the law to make a good youtube video or good content.
