The stats for September are on the ACTION website ( http://www.action.act.gov.au/About_ACTION/how-were-travelling-page). What's interesting to note is the drop in passenger numbers between September 2013 & September 2014. A couple of hundred may not seem many. But there was meant to be an increase in services for September 2014.
Just on fuel (ignoring the wear & tear) I spend $50-60 a week & that involes a 20 odd minute each way. Plus I only stop at 3 sets of traffic lights in total. I only drive as it involves me leaving the night before & I have erratic hours. Plus I have a long walk between the bus stops & work & a nice long climb from the bus stop to home.
