Re: dont do this to your Honda!
I was actually in door group and two of the requirements that we had and applicable to the above video are ‘door closing effort’ and ‘door sag’. Each requirement used the load data that the manufacturer gathered from the real life users. Doors are designed to withstand the repetitive service loads of so many cycles of door usage. If I remember correctly, doors are designed to be functional for 15000 cycles (15000 open/shuts). Some of those cycles were abusive loads and some were average operational loads. Automotive are designed to meet those requirements and that is it. Anything more would be considered over-engineering.
That is why I was so much ticked at that weirdo Jesse James who in one interview challenged the Ford engineers (after he pimped up a mustang) to design the car like he can. He was such an idiot not to realize that consumer autos are not about raw power. They are a good combination of power, safety, durability, economy and ergonomics. No wonder Sandra Bullock kicked him out of her life.
