why? because the foreigner usually gets the blame no matter what happened. A well known quote from the police : if you hadn't been there the accident would not have happened. And it is not a joke. Front and back camera is necessary and don't give the recording to the police but to the insurance company.
impossible to say if this is an issue for you since it is the airline that can - and do sometimes - deny boarding. Some airlines are strict and some are not.
