come on, you dont know a blind indicator and your a mod???
you know when ur driving down the highway and turn your blinker on expecting the lane to be free but once u actaully turn ur head, u see a car. the blind spot is what your mirrors can't let u see... the volvo has an alert system, which i dont know how it will work, like maybe once u put ur blinker on and someone is left or right of you it will go off...
