Retired BA/BY - you have no clue how things operate these days, so please refrain from positing nonsense if you don't mind.
Obviously, we all rely on engineers on the bay, and remote rigs with engines running to deice. We never, ever inspect the wings as pilots before take off. I have personally, as a 747 captain, never looked at a wing post deice. I just want to get to the bloody runway and get the show on the road.
Anyway, it'll all slide off before V1, so she'll be right!
