Bureaucrat: Ha! That bridge has excess capacity. If traffic gets too high, we'll just increase the tolls. Most of those schmucks don't really need to go anywhere anyway.
Civil engineer: Do we know that for sure? What if there is an evacuation or something?
Bureaucrat: That bridge was intentionally designed with low capacity to prevent invasions! Widening it would be a dangerous departure from historic bridge operations.
Civil Engineer: Aren't bridges supposed to be used to facilitate travel?
Bureaucrat: Yes, but only the right sort of travel. That's for me to decide! If traffic gets too heavy, and tolls get too expensive, the people can use buses. Too many single passenger cars anyway.
Civil engineer: Do you own a bus company?
Bureaucrat: Purely coincidental! I'm just guarding against bridgebuilder centralization.
Civil engineer: I see. No conflict of interest there. What's the name of your company anyway, Busstream?
Bureaucrat: BridgestreamTM, Smartass.
Awesome post, BJA!
