It's in traffic. In Europe. In an M5. Insane. And idiotic.
The driver, Giorgi Tevzadze, is from Georgia, a small Eastern European country that was in the Soviet Union. He is also apparently a nutjob with no concern for anybody's safety around him.
How he doesn't crash into every single person in this town is beyond me. Even though he doesn't, this is still monumentally stupid. The video says not to try this at home. In fact, here's the disclaimer:
We(including the driver) agree that driving on public roads like that is terribly dangerous and can lead to the worst consequences! so please DO NOT TRY TO DO what you see in this video! We are not going to race in streets like these anymore! But still this is a very beautifull video!!!
Yes, it is incredibly exciting. No, it's not smart. No, they should never do it again.
