Why 9.6% of Drivers Bribe Their Way Past Emissions Tests (And It’s Cheaper Than Fixing the Car)

In Mexico City, a strict environmental regulation—mandatory smog checks every six months—was supposed to cut air pollution. Instead, it created a thriving black market for bribes. This video breaks down the shocking findings from a study published in the Journal of Political Economy: how 9.6% of drivers pay just $20 to cheat the system, why only 1.5% of those who fail actually repair their cars, and why eliminating corruption could cost more than it saves. We reveal the hidden economics behind the bribes, the 'donor car' trick used by testing centers, and why the most effective policy might not involve individual drivers at all. If you think emissions tests are about clean air, this will make you think again.
