If you live in Manhatten, it is not all that unusual.
People live their whole life in New York City without ever driving a car.
Why? Because they are friggin idiots that like to live like roaches in an over crowded city that has over 300 miles of subway tunnels, over 10,000 medallion cabs, untold amount of gypsy cabs and busses out the yin yang so driving a car there just makes no sense.
You want unusual?
I have not had a license in 21.5 years, almost as long as you have been alive. Now I am finally trying to get it back and the 21 years worth of tickets was a staggering amount of money but I paid it and am only waiting on the reply from the New York DMV so I can goto the Cali DMV and get my license.
Go and get a license but do not get a car/cage. Buy yourself a motorcycle and really enjoy the roads.
