preference type "restroom availability"

I get that the restroom filter is a soft preference… but why?

When on long distance trips with family I think it's crucial for a route planner for 10+ mins of charging stops to include restroom availability if I choose so. As it stands now we have to wait at the charging point and then hoo to the nearest highway station to get a supply stop in that currently also takes 20+mins without the vehicle charging…

Not a very efficient trip to be planned
