Rumble strips are designed to jolt a driver back to alertness. Drift a bit to the side and the tires make a loud rumble, preventing countless accidents. In this era of distracted driving it’s been a godsend. Surely it seems we need the roads to protect us from ourselves.

Life offers virtual rumble strips as well. The scale or the waistline on our favorite pair of pants may jolt us out of our dietary habits. A terse letter from an angry customer may raise the customer service standards for an entire organization. A stern look has corrected plenty of bad behavior for generations. And in theory the United States has a system of checks and balances and regular free elections that act as rumble strips for bad actor surfing a wave of popularism for advantage. In life, when we drift off course we correct ourselves over time.

The thing is, the world is full of examples where the rumble strips didn’t work. Accidents, bad habits and behavior and yes, rogue actors in politics still happen anyway. That doesn’t mean we shouldn’t have rumble strips in place. How else would we mitigate the impact of drift?
