The removal of the middle doors is something that is symbolic of a cultural predilection of actively pursuing malfunction as a solution to a problem.
The removal of the middle doors was done at the behest of Dublin bus, this was there specification with the bus companies. This is the mentality you are dealing with, yet it is not unique to Dublin Bus. It’s endemic across all Irish institutions, of which there may be exception but I’m at a loss as I type.
If it takes on average 2 mins to stop a bus to unload/load the passengers and a journey has 15 stop, (it is more lily more), that’s 30 minutes not moving.
Perhaps pinsters might start to time the duration of each time their bus stops at a bus-stop on their most regular daily route. Then collect the data openly and allow play with with it. See if the assumption is correct.
