Well being car free to me isnt hard.
I am only 16 and cant drive.
I don't use the bus to college though , I just prefer to bike the 6 miles (its ok in the morning because there is some good bits to just roll downhill)
When I turn 17 , I will learn to drive but even then I will probably only get an electric car like a G-Wiz
Helps the environment. That is another reason I plan to be car free.
