Step-by-step explanation:
Let's draw it out:
Car 1 going Strait = x
Car 2 going left = y
A pedestrian walking straight. = z
In the "natural" rule of law with lights, it would be a left turn. But here, there are none.
So it should technically be the x to go first, then the y & z.
But in reality, y & z would have the right-of-way.
