You can't place the track at a place where it would violate design rules.
You can switch to the open gl canvas (F11)
go to preferences->interactive router and change mouse drag behavior to interactive drag.
Then you can use m to drag similar to the drag in legacy.
But the interactive drag moves stuff out of the way for you instead of simply not allowing you to drag. (If it can't move something the trace you drag will "walk around" the obstacle.)
