3D editing removes any time wasted lining up elements that require continuity over multiple panels that are not adjacent on the 2d map. High quality UV maps almost by definition have panels all over the place so fill in the entire texture to get the highest detail possible... so pretty much most cars are cut up in a way that isn't all that intuitive when just looking at the UV map in 2d. The majority of my slap-dash liveries tend to be very stripe heavy specifically because doing stripes in 3D is about the biggest bang for the buck. I imagine your green stripes would be a complete pain just looking at it in 2D, while in 3D that'd take no time at all.

I've done entire skins in 30 minutes that were just a bunch of well placed stripes and my usual smattering of logos.
