. So, as long as reverser has not been selected I recommend to go around. Automatic roll out was, for an CAT IIIB approach, not planned just for fun.
Once you have the wheels on the ground, if not a balked landing of course, the reason for going around must be major. Pilots are trained to abort a high speed take off in low visibility conditions. The chances of being capable to decelerate the aircraft on the runway are very high.
Think about going around. Of course first thing you check is the fuel you have left. If you are landing in a not very busy airport, probably you will have the chance of trying another approach. But imagine doing this in LHR, CDG, MAD...etc. The time it will take ATC being able to vector you for another approach can be quite long with a busy airspace and an airport operating in LVO. You can put yourself in a situation declaring emergency fuel, or diverting, when minutes earlier your aircraft was with the wheels on the ground, but automation was not able to do the rollout itself. Pilots are in the cockpit for a reason, and they are trained to take action when necessary.
