Izi zikutanthauza kuti, m'malo ovuta kwambiri, chiphaso cha ID chikhoza kusiyidwa m'galimoto panthawi yopuma masana popanda kudandaula nazo, komanso kuti makina osungiramo makadi pamalo oimika magalimoto ku Toronto safunikira kuchotsedwa mpaka madzulo. Makhadi amenewa nawonso ndi olimba kwambiri, choncho akhoza kugwiritsidwa ntchito kwa zaka khumi.

Tidzachita zonse zomwe tingathe kuti tipitirize kukwaniritsa zosowa za makasitomala athu popitiliza kupanga, kupanga ndi kupereka zinthu zatsopano komanso zapamwamba kwambiri.a
