After driving along a 2 lane road, to pass the line of cars in front of you on the right when the road spreads out to 4 lanes at intersections.
I cosgroved 2 cars at the intersection.

I had a 3 cosgrove at the intersection (I passed 3 cars on the right).

I had a negative cosgrove at the intersection (cars passed me)
