TL; DR
Efforts to make cities car-free illustrate why innovators must ensure that the purposes/ agendas of their work are truly "must do's:"
Innovation work actually needs "must-do" purposes for two reasons.
It's not just because it's rational for people to reject changes (that might be for the greater good but hurt them personally).
It's also because human psychology, especially Loss Aversion, causes people to fear the downsides of changes more than they get excited for the accompanying upsides.
To make a change stick, you then first need to make it happen despite this gut-driven opposition and then make it through the "Goodwin Curve," the waves of post-implementation opposition, until the "new way" becomes a fresh status quo, and people have personally experienced its benefit.
