Snow emergencies are a big deal here in Minneapolis. You hear about it on the TV news. There’s an app–tens of thousands of people have installed it on both iPhone and Android (“avoid the cost and hassle of a ticket and tow…”). People are very interested in not having their cars towed, so people become very interested in moving their cars to designated areas.
The reason the City of Minneapolis makes a big fuss and puts so many residents at risk of serious personal cost, inconvenience and unhappiness is that we’ve collectively decided to make it a priority to keep our streets plowed and safe. Individually, people comply with the rules because their personal interests (money and property) have been aligned with public safety (plowed streets).
