Eh, that discourse is usually being advanced by people who never ride the bus, don't intend to start riding it, and have a personal interest in selling you a car. In real transit preference surveys, and historical outcomes, it is clear that people would ride a bus that goes to their destinations, comes often and reliably, and is reasonably priced, without regard to how many mental cases are aboard. So if a transit agency faces a choice of spending limited resources on policing the inside of the vehicle for lunatics, or adding a bus to the schedule, they should always choose the latter.
“it is clear that people would ride a bus that goes to their destinations, comes often and reliably, and is reasonably priced, without regard to how many mental cases are aboard”
If you believe this, it would be cause to doubt your sanity.
