Re: Free buses
"Either the people who user the bus pay for their use, or everyone (regardless of if they use buses or not) pay for the buses via their taxes."
Or option C), good, clean, free public transports pays for itself by bringing people, business and money into the town because it's a "public" service designed for the "public" to use and benefit from.
Oh, and since you ask, yes the sky is pink on my planet.
