You came along with a stupid presumption
"talk to driver again?" and you don't
even know what was the content of the communication being
exchanged.
You sound confident with the "again" that it was about
that guy "talking to BC about how is the bus and later end up an
accident is a tragic."
Really, maybe that guy was asking about the
route....or just happen to be standing there preparing taking
out his wallet for coins, or just happens to be there....lol
Understand now why your question was stupid?

question mark is not there for nothing. Let me explain to
you why I am so serious of pax talking to BC.
Most of time, when pax talk to BC esp when they are leaving the
stop (turning out), their attention and focus are diverted.
They just turn without watching oncoming cars. Similarly to cyclist
on the road. Someomore this is a new bus, let take good care of
it.
If you were a driver, you will know how disturbing is a person
asking you question when you are driving.
Previously, I heard that a guy (should be a bus fan) was scolded
by the bus inspector onboard. He was talking and asking
questions regarding the bus schedules.
Please know the dangers of talking to BC onboard.
