Wait until you're like 23 or 24. Insurance drops down ALOT.
Until then, you have several choices:
-Pay the annual coverage fee of +$1k
-Not drive a car
-Ride the city bus
-Taxi
-Bicycle, moped, goped
-Ride with a friend
-Whatever else you can think of w/o you being behind the steering wheel.
-Or just drive w/o insurance, like some people do.
