I'm familiar with the type of road the OP is showing, and very familiar with what they're like when they get jammed up. When you have a line of 10-20 cars queued up in both straight-forward lanes, and you're in the middle of that queue on the right lane, when the traffic starts moving finally then all that traffic behind you has nowhere to go because the lane to the left is also bumper-to-bumper. People starting getting anxious and angry. For that reason I would take the sidewalk in that location, simply because there are so few curb cut driveways along there, AND you would get to bypass all that traffic easily!
If traffic was moving along steadily with only a few cars having to queue up at lights then yes I would definitely be in that right lane with the sharrows.
