9464	warn on unreachable/unescapable oneway roads	aceman	team	"I propose to add a new check to the validator to show a warning if this happens simultaneously:
a) 2 or more roads meet at a node and all of them are oneway=yes (or -1)
b) the oneway direction of all of them is either towards this single node (junction) OR away from this node

This means there is no way that would allow traffic to leave this node or flow into it.

Whether you also check each traffic mode (foot, bicycle, motor_vehicle, etc) individually is a bonus depending how hard that is (e.g. if 2 highway=primary are oneway into a shared node, but there is a footway allowing ""traffic"" away fromt he node, it is not enough for motor_vehicles)."	enhancement	closed	normal		Core validator	latest	duplicate
