I do this everyday as part of my commute, which is odd because I live in the UK. This is because I go through a busy one way system with one section that has four lanes. Because of the set up of the road and the volumes of traffic at the time that I use it, I enter this section and immediately pull to the to far right-hand lane, travel the 200-250 meters of the lane and towards the end merge over to the middle right lane to get out of a slip lane to transit interchange. The road then changes into a multi-lane rotary system and further merging left is required to exit the system at my turn.

Merging left in the one-way system is anathema to car drivers and needs to be done with caution. Rather ironically its very much expected on the rotary which adjoins it.

Off topic, but I think in a sense related; what is the VC position on roundabouts/rotary systems that are effectively multi-lane due to their size but lack definitive road markings except a short disctance preceding any light controls that are in place?
