Menene tsarin bumper?
Menene kwarangwal ɗin motar? Shin itace fitilar motar? Idan ba haka ba, menene alaƙar da ke tsakanin su biyun?
Kwakwalwar bumper da bumper abubuwa ne guda biyu daban-daban, kamar yadda bambancin nau'in mota ya bambanta, aikinsa kuma ya bambanta, yawanci a cikin bumper, bumper yana kan firam, duka suna da irin wannan alaƙa, kun san da yawa, ba ku san yana da taimako a gare ku ba! Af, kwarangwal ba katako ba ne, yana aiki ne a matsayin kariya ga jiki, musamman ɓangaren injin!
