 And now, great moments and unintended consequences. Part 1 Road Kill The year 2012. The problem? Driving fatalities on Texas roads. The solution? Implement a simple cost-effective awareness campaign by displaying crash death totals on highway message boards. Sounds like a great idea, with the best of intentions. What could possibly go wrong? In order to read these messages, passing motorists must look away from the road. Accidents along roads with new displays increased by 4.5% within 10 km of the sign, according to one study, amounting to an additional 2600 crashes and 16 deaths per year in Texas. Not good news, considering more than half of states in the nation have deployed these signs on their old, what's that over there? Part 2. Bottle Throttle The year? 2013. The problem? Bottled water consumption at the University of Vermont is creating too much waste. The solution? Eliminate water bottles from campus vending machines, hand out reusable containers and spend a hundred grand to add filling stations around campus. Sounds like a great idea, with the best of intentions. What could possibly go wrong? Students don't always remember things, like their reusable water bottles. Faced with limited choices, a study revealed the demand for sugary drinks on campus surged 25% and plastic bottle use per capita increased 6%. Some ideas should not be recycled. Part 3. No Way Fiancé The year? 1900. The problem? Argentinian bachelor sucking up valuable resources without producing more citizens. The solution? A bachelor tax. A strangely popular feature of the time, but with a special waiver for those gentlemen whose proposals were turned down. No need to pour salt in that wound come tax day. Sounds like a bizarrely antiquated idea. With the best of intentions, what could possibly go wrong? The tax exemption gave rise to an entirely new vocation, professional rejecters. These entrepreneurial ladies would swear to authorities that a gentleman tried and failed to win their hand, all for a fraction of the cost of the tax itself. Proving the old adage, you can't buy love, but rejection is on sale. This has been great moments and unintended consequences. Good intentions, bad results.
