Why don't questions collide in transit?

Question

or at least pause in mid-air to talk to one another

Answer 1

They do, but being non physical, just pass through one another without pain or suffering.  Some pause and chat, if the mood is correct :))

Answer 2

Why not?

Answer 3

how do you know they don't?

Answer 4

Few years back (on yet another server) two of us, sending information to same board...lost our questions entirely.

Two weeks later, they showed up...we always wondered where they'd been for that time. They never told.
