You have to have real options or people can’t make informed decisions.
I have a background in city planning, and in the US, you’ll constantly hear about how trying to make cities more friendly to pedestrians, bicycles, or public transit is a waste because no one uses it. But the truth is, most people will end up using the system you design. If you build a system just for cars, people will use cars. If you build a city around public transportation, people will happily use it. If you build a walkable city, people will walk.
