ELI5: Why such a high age limit to rent a car compared to other age limits? (Smoking, drinking, etc.)

Age limits for smoking and drinking are set by government. They get tax money for your vices so they let you start as early as they can justify politically.

Rental car age limits are corporate policy based on the statistical likelihood that you will total their car and send their fleet insurance through the roof.
