The age at which one can finally rent a car in the United States without being charged enormous amounts of money and without having to sign thousands of papers for that matter.
So, a half-blind 70-year-old just got his license, rents a car a kills 5 people is more acceptable than a 24-year-old who has been driving for up to 10 years without an accident.
"How was your trip to New York?"
- "Fuck that! I got stabbed and mugged in the subway because I woulda had to pay $100 more per day for renting a car cuz im not 25 yet!"
