Yes whichever button I press the lift arrives.

Corse it does, but it will arrive quicker if you press the correct one.

In theory in an empty lift, problem is this IS NOT the case with students
using them. Whether it's going up or down it's best to get in with the
trolly forcing the students out and making them walk a flight of stairs,
otherwise you will be there for far longer, usually I only use the lift
when I know studetns are in lecture rooms and labs. They are usually out
and roaming the college like zombies in shaun of the dead on thre hour
and sometimes on the half hour.




It's simialr to the pedestrian crossing buttons.

Nothing like it, those don't indicate which direction
you are going, just that you want to cross there.

and how does indicating you want to cross change anything ?

You are right in that they rarely alter the time when the vehicle
signals are green, but sometimes the overlapping red phase for
pedestrians to cross doesn't happen at all when the button is not
pressed, especially when there is a filter light.
