that's hot!
Well as long as you are properly licenced you have nothing to worry about, thats an old video that I believe has been used in a couple of meetings where regulations have been discussed. Its exactly why regulations are coming and was foreseen by the CAA in the UK years ago. That's a rule 5 breach straight away then flight outside of VLOS.
Who will police it, not the regulators but those that have jumped through the hoops to get their licences, they will quickly tell the authorities.
