The "memory" pass of quite a few routers will route this correctly, single layer. Where they fall down is if you offset the connectors or some other previously routed connection interrupts the pattern at the beginning. Yes, they are not really recognizing patterns, as we generally do. Humans are actually pretty good at this, it may be quite some time before the machines catch up. Nevertheless, routing pattern recognition is the obvious direction for routing technology to go. On the other hand, much simpler, we'd like some fairly simple cleanup routines. There are places where the router could be vastly improved without major advances in artificial intelligence, and getting rid of those meanders approaching off-grid pads is one place where this is the case.
