Thanks for the comment Vijay. At an intersection with a traffic light, there is a section for scooters only where the first 1–2 cars would normally stop. Thus scooters can cheat up and go to the front of the line at a red light. Once the light turns green, all the scooters who have arrived at the intersection (and gone to the front) lead, while cars follow. Without this design, scooters would probably cheat up and wait for the red light in between lanes, which is more dangerous once the light turns green.
A second example is the left turn — scooters are not allowed to turn left on green. They can only go straight ahead to the corner on the right, stop in a designated section, and turn the direction of their scooters left. In this way they join the cross-traffic scooters once the light turns green. Instead of one left turn, it is 3 motions — a straight, rotation of scooter, then another straight.
