He was doing you a favour by giving it a good thrash - after all, thats what its for !
Agree idle isn't great, sure it warms the engine but not the transmission or drivetrain.
As for thrashing it when cold - I don't often but feel it appropriate. What a load of <beep> rubbish.
Pretty much all engine wear happens when cold and with cold oil it won't flow so you've got metal on metal contact. The best way to warm a car is to treat it like you've got a brand new car and running it in. Only takes 10 minutes so what's the big deal.
I've personally seen warranty refused due to this behaviour on a £15k engine failure on a new car and the decision was upheld in court.
Nothing wrong with thrashing but everything has to be up to temp.
Doesn't matter if you think the speed is right or wrong, the cold hard fact is sombody was driving the car at license losing speeds like they stole it. The way I see it is that it MY car and I want it driven exactly how I want it to be. Not what some technician feels like during a joyride.
