I feel, mate. I've been racking my brain about this topic for 3 weeks. I can't recall ever seeing Superman do a super speed rescue of dozens of people in any of the comics, shows or movies. He always swoops in to save Lois, or can save a train/plane/boat full of people. But never multiple individual passengers at the same time.
I'll keep pondering. In the meantime, more Flash and Superman races.
