Temporarily Closed Roads

If I enter a future date during planning and a road is closed today, ABRP plans the trip via a detour. But this shouldn't be the case if you've deselected "Real-time traffic" in the settings. What would be the point of specifying a date for the trip then?

When I plan a future trip, I do it to determine if, where and how often I need to charge, or how long the trip is likely to take. Roads closed today are then irrelevant and shouldn’t be taken into account.
