I think the time is coming to fit a permanent dash cam to the bike, earlier today I also had a Tesla driver almost reverse into me, I was very restrained and told him to be more observant in future to which he agreed to, he had his family in the car, hence my calm demeanour, by the look on his face it was far more threatening than giving him both barrels. His wife looked doe eyed at me and then told him off, that’s the Harley effect.
