I need 6 lanes so that I can drive as fast as I want and pass EVERYONE! Especially those people who are already passing everyone else, those slow bastards!
Going 90 in a 70 saves you 23% of the drive time, or a whopping 14 minutes per hour of initial drive time! That's definitely worth the speeding tickets and reckless driving charges!!
and it's also generally good allegory for using too-simple of solutions to fix problems. Throwing more y at problem x that is still alive and well with plenty of y already around is a classic failure. Hell, it's the basis of a few fallacies.
