Cultural differences. Think of pandemic days, and how each country/city operated. Despite having almost no official lockdowns, Tokyo operated in self-induced lockdown style as people didn’t really want to exacerbate the problem. It was kind of the opposite in other places.

People in Switzerland might consider other things as the main goal (making the air cleaner), and this could be a simple nudge to change their behaviours. It’s not always monetary competitiveness that shapes behaviour.
