I didn't notice in this case, but I think most school buses these days have convex mirrors as well.

Regardless, it's exactly because of that blind spot that the bus driver should have waited several seconds before starting to merge into the lane. Luckily, he didn't zoom into the lane on top of the car like he zoomed back into the lane in front of the truck later on.
