Please explain to me....

So you're driving home and it's rush hour. You come to a stop light at a fairly major intersection where you want to turn left. The road that you are turning onto is crammed with traffic and the cars are all the way up to the intersection. You get a green light to turn. If you have nowhere to go, WHY THE FUCK WOULD YOU TURN AND BLOCK THE FUCKING INTERSECTION?!?!?!?
