I don't know what TS had done to him before the video, but the
Hyundai driver pretty much deserves it for what he is constantly
doing.
I believe the biker and the driver of the VW Bora is aware of
what is happening.
TS might be recording without permission, but that video itself
can be used for pictorial evidence. Hyundai driver was obviously
asking for trouble.
EDIT: Ok, my bad. TS is not the driver..
