maybe to them, half standing is very few passengers already
or the app is not real-time enough
if u see red (can be literally, u know...) will u wait for next
bus?
or when the bus arrive, u still try to board?
so this app is quite useless right?
It can be useful sometimes...
Let's say from A to B, you have a direct service X, or you can
take another service Y and transfer at somewhere
else which may take a longer time. If you check
the app and see next bus on sv Y will arrive in 2 minutes and it is
quite empty, while a packed-to-the-door bus on sv X will arrive
in 5 minutes and all the subsequent buses are also full, would
you still wait for sv X? But if they did not tell you the loadings,
you may keep on waiting for sv X (since you already missed the bus
on sv Y anyway).
Just saying...
