I ride a stretch of four lane road where the right lane narrows and the left lane gets backed up where a road T's into the four lane on the left, a few blocks later the four lanes narrow to two. I'll pop on the sidewalk for half a block as there are vehicles dodging in/out to clear the slow left lane and pass on the right in my lane. There are too many people entering intersections with cell phones to their ear, big trucks who can't stop or fast cars darting in front of big trucks I opt to take the empty sidewalk for 200' and re-enter where the right lane as room. To not do that exposes me to more danger than I need on a daily basis.
