Maybe buses should be free
Seattle used to have an area of downtown where you could ride the bus for free.  (You could ride within the area free, but paid if you rode out of the area or started your ride outside of the area.)Busses became makeshift homeless shelters, which probably ended up driving away actual commuters.Seattle also bought fancy self-cleaning toilets many years ago in order to give tourists a place to go and to reduce public urination by the homeless.They ended up selling those toilets on eBay a few years later because the toilets had become a place for addicts to shoot up and for prostitutes to take their customers.Free is probably a bad idea...
