Most public transport options also offer weekly/monthly/season tickets that work out considerably cheaper.
Anybody actually looking for a job would factor in costs and feasibility of getting there.
I'm going back a few years now but I once was considered to be an unsuitable candidate for a job because of where I stayed. At the time I stayed in East Kilbride and the job was in Hillington. There wasn't a direct bus at the time but I could have done it by train no problem.
It does pose the question though, if you're an employer and you are aware from previous experience that the public transport from a particularly location is notoriously poor, do you consider applicants from that area as unsuitable?
I can get a return on the train for just over £4, by bus just under £4 or by cycle - a pittance.
