People get drivers licenses in order to drive, and they get credit cards to take on debt, build their credit, or make payments quicker and easier.
Drivers licenses don't make people drive poorly nor do credit cards make people make poor financial decisions. If you're going to convolute the two through some form of causality, the argument you could make is that people who are apt to make poor financial decisions are more apt to pile up credit cards.
Your claim that getting a drivers license is the "worst safety decision a modern human can make" is pure hyperbole. What about not putting on a seatbelt? What about not checking their tires and brakes regularly? What about failing to adjust their mirrors? Those are the actions that reduce safety, not getting the license, much like buying that HDTV you cannot afford reduces financial standing, not getting the credit card.
