I have a circuit controlled safe crossing on my rails for players, and have run a road for my transport drones across it. When the drones cross, the gate shuts stopping trains, however when trains are crossing and shut the drone/player gate, the drones phase right through the closed gate and the train itself. Is it possible to cause them to collide with the closed gate but pass through it when it is open? I'd be happy even with the little wobble they do when you destroy a road in front of them while they figure out a new path.
