Original Welt ?
Here's a photo of some original welt from a 1970 Cadillac. Why are the relief cuts made like this and not just regular cuts ?

made that way to go around any curved areas and not kink up.

That, I know - but why do they go through te extra step of making it so big ?

I would think it is when they make it not to bind in the machine, also this helps when you sew it in.

It is made that way because that leather welt is heavy, and on an inside corner if the welt just had straight cuts, it could overlap itself and make a bulge. This way you can sew it to an inside corner or an outside corner and it won't overlap itself. That was sewn on a dedicated machine that sewed the welt and had a cutter to make those round notches. There are all kinds of dedicated machines in a sewing plant that only do one operation. The parts of your Cadillac seat from that long ago would probably have had the edges of the seat parts run through a serger which would have cut off some of the fabric and made an overlock stitch on the outside edges as it sewed the leather to the sew foam underneath.

This piece is made from vinyl.

Whatever, the principle is the same. That's just how that particular seat cover manufacturer made their welts.
