On the holey thing in on the steering: Those aren't functioning as holes! they more function like Spokes on a wheel!
You can drill holes to make spokes, you can drill holes to receive Bolts and pins and shafts, to get a desired shape etc. As long as you intend for holes to be there in the beginning.
Hence If you design the object to have holes at certain points.. then those are not really "bad holes" because that is how the object was meant to be!
This is an example of "Good holes" I think the purpose is light weight and maybe to help air flow. The structure was designed to have the holes in place.
When the original poster says "drilling holes" I am thinking of somebody drilling a hole into an object that was not intended to have a hole, or an object that does not need holes for whatever reason. That is very dangerous especially when the person is not aware of how much the object is weakened by drilling those holes.
