I mostly stop left with enough room for drivers to turn right to my right - about half of them pass and turn, if not and their signal is on I point to the pavement to my right. About 1 in 100 will pull up next to me and go straight on green, no big deal, I go too and tuck in behind them as we get up to speed. If this happens it usually means I am too far left, only give enough room for right turners to get close to curb to turn.
If there are no other vehicles stopped I stop on the
center of the quadupole sensor.
