Many years ago, when I hopped in for a semi trip with hubs, he explained the USA interstate highway system to me.
He also explained what the drivers in their unique CB radio lingo were referring to in terms of the lanes on the highway through cities.
The left lane next to centre was the “hammer lane”, meaning that you had to hammer down (accelerate) in order to pass.
The right lane next to centre (excluding exit lanes) was called the “granny lane”, because this is where the slow traffic should be.
The centre lane was appropriately, the “sandwich lane”.
Our indoor track has three lanes, but they operate opposite to the highway. Our hammer lane is to the right of centre and granny lane is to the left.
The gal in the hammer lane in my feature photo had just passed me.
I’m usually a sandwich lane kinda gal, unless someone’s speed has them in the wrong lane. Then, I’m hammer lane all the way.
And then there are those who don’t play by the rules of the road and take up all three lanes at a less than normal pace.
As I come up behind groups like this, I call out “passing”, and the person on the right moves to centre.
Next time I’m going to call out, “hammer lane”.
