You was impatient, you tailgated, you attempted to overtake and failed (yes the dashcam car may have sped up to block you overtaking but please remember that a speed limit is a maximum speed permissible - it doesn't mean you have to drive at that speed)
And then because of your frustration and reckless driving you paid the ultimate price but you attempt to blame the dashcam driver?
This silly idiot parks at a give way junction like he's waiting to turn right !! Then goes to pick his children up leaving other road users at risk of collision and pedestrians (including children that have just left school) at risk of being hit by a car/bike because of his inconsiderate dangerous parking !!
I'm guessing with parking skills like these his driving must be abysmal !!
The jesus of drivers. If only all drivers were like him
