As they share the same extension tree, current haulers and gathering bots suggest that sequer is newb hauler for 'small' range and volume logistic (like empty a can) and Lithus for small range / mid volume for the same purpose. But they do it very badly probably for some reason you explain. It must have a strict distinction between mining skill for mining bot purpose (miner AND short range / volume logistic), and the large volume / long range logistic.

I think a good alternative is up like by 50% for sequer and 200% lithus (price concordance) for mining purpose and to add new advanced hauler requiring a new skill (like Spec. ops robot control) with Industrial robot control prerequis. Like assault Special sequer for long range hauling with same volume transportation than sequer but a little faster with somethink like signal masking bonus for tactical hauling purpose and a huge hauler without def bonus and a bonus like 1% bonus in speed. If the skill is rank 9 and prereq for large hauler like 8-9, it will be very hard to get due to the two condition (logistic rank and industrial robot control rank).

It make logistic less painful for miners and the need of logistic specialist for the large volume logistic. There will have less specialist in logistic than lithus pilot actually due to the new skill to get (most off them will make miner), so finaly, same volume transported but less painful for the pilot (more with the coming waypoint changes).

PS : and during that time my can holder alt disconnect and ... zo , no can, no more hauling needed
