If you work in a planning firm, city, political office, think tank, etc. where you might get fired or disciplined for mentioning or proposing the idea of urban gondolas, you probably didn’t want to work there in the first place.
Places like that are interested only in gatekeeping and maintaining the status quo. They’re interested in scaring you into obedience. Like we do with dogs.
You deserve a work environment where your opinions and your ideas are valued. Even if the ideas are ridiculous, you deserve an environment to express them, play with them and maybe even realize them.
You’re not a dog. You don’t need obedience training.
