Gimpy, there is NO excuse for letting yourself get rear ended. THE ONLY THING YOU SHOULD BE DOING AT A LIGHT IS LOOKING IN YOUR REAR VIEW MIRRORS,FLASHING YOUR STOP LIGHT, AND GETTING READY TO USE YOUR ESCAPE ROUTE SHOULD THE NEED ARISE. Otherwise you are allowing your life to be put out by the next idiot that is not paying attention. Hope you remember that sore back for a long long time, it may keep you alive the next time. Sorry, no symp from me. Vegas
