This only works if a car is tailgateing you, as for someone who pulls out, i've actually chased people down before and when we got to a light pulled up and been like WTF WAS THAT ABOUT!!!!!! On the other hand i always expect someone to pull out in front of me. As for spring hill dr fuck that, a good friend of mine died on that road a while back, and i've had some close calls too. I hate the old people in the hill
