That blows why does the sister get to have a car and insurance and you don't?
My parents wouldn'y let me have my own car until I got to college.
They figured that way they can take it away from me.
But, I had to pay the cost of the increased insurance. Especially since
I increased it by rear ending a guy in Boston within a month of getting my license. Boston Roads are like suicide paths. My sister put me up to driving her back to college.
So my sister and I had to share.
Good luck and hang in there. Get your sister grounded so you can drive her car.
