Available from 1932 to 1953, the minibus Leyland cub definitely cost too little per km -- $0.10/km; while a similar bus, the AEC Reliance cost $1.25/km for 5 additional passenger. I doubt if the cost was intended to be $1.00/km but being miss-typed?
Well maybe it is too little, but on the other hand it is the one of two buses (the other is Guy Special) that is profitable for city transport.
At least in simutrans standard, I could not make profit with anything else.
Thank you for spotting that - found and fixed for the next version.
