I didn't realise at first but, if this was implemented, it would take out a few private campsites on entry to Porsche Curves. I don't realistically see how it can, or needs, to go that far back. The existing gravel trap is tiny in comparison to this. It would look like the first corner almost. The more I think about it the more it couldn't happen.
