A road map that the main road is not controlled by a human at all is going to be vague. It's like letting 10,000 cows loose at one en of a paddock and then asking for the road map of which way they will travel to the other end for feed and water.
The whole idea of drawing up a map for something intangible is just stupid, all it is for is opposition screamers to yell at something when it doesn't go exactly as planned. Where every educated person knows, we are waiting on the right signals to open up, so the goal posts are variable depending on what the virus does next. It's like lets draw a road map for our way out of Afghanistan, and then the Taliban don't follow your rules, dammit, why didn't they stick to our plan....
