Its all about the experience people have in the toll free period that will set the scene for when tolling commences. Three out of four of your trips were slow (the reason is probably irrelevent). My trip north on Sunday was hideously slow. If it's happening to us, it's happening to other potential users as well.

This toll free period should be demonstrating the time saving and fuel saving nature of the tunnel. It seems that, for a good part of the time, it's not doing that.
