This would be section 1.3 right below stop point. All the other sections from current 1.3 Category would move down to 1.4 etc.
Parking lot road u-turns
Enabling the u-turn on a gas station's parking lot road can greatly enhance routing, especially when the gas station was an added stop to the final destination.
Some gas stations do not have access to both directions of a road due to medians or turn prohibited signs. Enabling the u-turn can give much shorter, faster and realistic return routing to the continued route.
Corner gas station example
For corner gas stations that have one PLR and don't have access to left turns at the exits, enable the u-turn on both ends of the PLR.
