Cars are not moving in P3 -> C3 -> 17 position

Found issue, Debug line 222. And start from there.

There's an error when using get intersection light state, where intersection 11 heading to 17 does not have an object.

Instead of looping neighbors we need to loop the ones that are in-degrees

[mjcortejo]

Must use G.predecessors to loop all the neighbors instead of everything

lol fixed by using predecessors
