I can't see how that can be achieved. Hi Mark! Is there any chance for this patch to get committed in the near future? I think it would be very helpful for routing (also with barrier=cycle_barrier/gate/lift_gate etc) and the case of target and/or destination being too close to the barrier is not that common. Thank you for any info! -Martin
