I want to animate the cars at an intersection on google maps. I think I am pretty close to finding the correct expression. I have a test project I am working on to figure this out. The row of cars at the top move when I click play but they all run into each other at the red light. The cars at the bottom don't move but the car spacing is correct when the cars stop at the red light. I am trying to find out how to get the cars on the bottom row to follow the leader car or null object.
