The difference is that the barriers to implementing a grill block are about non-existant. I think the first one was wet newspaper or something, any sort of material can be bodged into a grill block (of varying durability), you can prototype one with coloured duck tape, or even cram neglected beanie babies into your grill.

VG's for fuel efficiency are surrounded by mystery, or bullocks if you prefer. There is no end to the number of things you could be told you are doing wrong after trying them, it isn't well defined how it is supposed to be helping car efficiency. There simply is no defined theory as it relates to efficiency or it's application. The potential here seems not worth mentioning in the "I think someone else should try this" sense, what you do with your own time is a different matter.

I'm confused, you don't think these other people did proper testing? On what basis?
Google Custom Search

Can you properly define proper testing of vortex generators? Can you also define proper testing for non-existence of invisible pink unicorns?
