Flashing lights and beeping horn behind me... If I am stuck behind someone else... I am staying where I am. If there was nothing in front of me, I would (because I use my mirrors) have seen him coming and got out of his way before he would ever need to flash me. There could be 12 cars in front of me and still they flash. Well they can get as excited as they like, if they hit me from behind it's automatically their fault. Oh... and just in case you think I am a slow driver, I am not... promise ;)
