Most city-dwellers don't *need* a car nor to know how to drive. It's a convenience and we're a lazy, gluttonous, obese society full of whining liberals.
A job is not like driving which can get you and others killed. You can start paying taxes as soon as you drop from the womb. Be a parent? So can 11 and 12 year olds if their bodies are matured enough. Drudge just had a story on one girl that young in the UK about a month ago. The military has standards: you have to be at least 17 (with parental consent).
Life isn't that dangerous by itself. Stupidity is dangerous. Teens don't need to be on the road after dark without justifiable cause (leaving work). Safety, especially with driving which is NOT A RIGHT, should be the first priority.
