When I use the city/filtering mindset in my city(which is a moderately easy one), I have found the lane space on the left lane of the 2 lanes same direction (one way format) to be more effective than the right. I know some Frap pushers object, but the ownership of lane in such context is less defined in practice and therefore 'when in Rome' applies. Left of left lane is passing on the left, drivers are on the left which allows direct vantage of the driver in the mirrors and the door zone is less populous as the right side. When using that model, I usually get halfway to the next block light before the car behind is even close to needing to pass. Even that is subjective since the peak speed limit is 25mph anywhere in the city and lights are every block. Considering in a car the cars are disrespectful of any gaps or hesitations, I do not consider it any different with a different mode other than I chose a mode which offers more freedom and sensory awareness. We all end up in the end game at the same time(sometimes I get a several minute lead over 3 miles).
