I just don't get why people are filming this stuff???? If you intend to break any limits or laws, leave the bloody camera at home as all you are doing is tearing up your own license at minimum. A camera is great for a sensible day out and catching someone running into you or pulling out on you, but if they see 100+mph, wheelies, etc, they you are going to be in the wrong and lose your license, and it don't have to be a dash mount to work out 2 fixed distances on a road and how long it took you to get between them. I just honestly don't get it.
