I think the Safety Car has its place just like the Virtual version does. You could argue about the number of different yellow flags being a little outdated now we have the VSC. I mean, isn't there still Static, Waved and Double Waved?
What you don't need in a sport which is already complicated is more and more complicated rules. Bunching the pack and unlapping cars so everyone is 'line astern' is simple and easy for fans to understand.
What is needed, is the rules to actually say 'The Procedure to remove the safety car and restart the race is...' followed by a clear, bullet pointed, step by step process of doing so.
