Frankly I could excuse stupid ideas like the titanium rubbing strips to make the show more visually interesting. That kind of thing is harmless.
But a standing start after safety car is not harmless. There's just too much chance of collision, of someone having a poor start and losing out that position. We've seen too many cars swamped at starts and lose out track position. It doesn't seem a reasonable thing to risk that much a shake up of the order just in the name of improving the show. And what about false starts? If someone has an engine problem and stalls? What will the abort procedure be -- everyone stops their engines and we do a full start routine, or what?
