yeah but that doesn't make really sharp angles and controlling the curve where it bends precisely is hard, fighting that is going against the claim it's about manufacturing efficiency
There are multiple dimensions to manufacturing efficiency, though, right? I have no appreciation for the cost of a couple dies and a machine for stamping versus the cost of a CNC break with one die, but it may play a part based on the number of units they think they will sell. (1,000? 10,000? 100,000?)
Springback is possible on a press brake when folding along a single straight line. If panel needs a 30 deg bend, then bend it to 40, and it pops back 10 when off the press brake. As an example.
That quickly gets impossible to do when you start bending around complicated 3D contours.
