~100 restaurants teamed up, have salaried drivers, and an app. I've been told it works well by locals.
Most importantly, I've never heard anyone using it, so it wasn't done right.
I'm confused about what you mean here.

Correct. The model rewards people for piggybacking because it incentivizes them to choose a restaurant that might not have been their first choice.
To avoid being the "instigator", you can just always choose to piggyback. It's always an option in my city.

I also don't understand this, but perhaps you meant it in a context other than UberEats.

Many people won't realize they're using it. It shows up like a delivery discount: "Order in the next five minutes and pay $0 for delivery" or something like that. Everyone UberEats user I know uses it -- some exclusively. We never talk about it though, this is just what I've observed when watching them order.
