I'm not sure I fully understand your use case? Why would you be looking at the map in the middle of a fast descent like that. Were you already not aware that you'd have to slam your brakes on halfway down the hill for a right-turn before you even started the descend?
And I think the argument holds even less water in a fast group ride. Does no one in the group, especially the people at the front know where the group ride is going? If everyone is half lost, surely it'd be going pretty slow while someone calibrated where the group should be going....
