You cannot use their* cars without costing them additional insurance, and maintenance, and inconvenience.
You do not have to have a car to get honest work for decent pay.
Ride a bike. Take the bus. Walk. Ask a friend.
You’re parents do not now and never did owe you a ride. They don’t even owe you soccer. (gasp)
My teenager managed to get a job and work all summer (and still make it to all his swimming practices and meets) without a car. He rode his bike or asked a friend. Usually we couldn’t give him a ride because we were working too, but if we were around and he asked we’d give him a lift.
Driving is a privilege, not a right. If your are mature enough to drive then you are mature enough to figure out a way to earn the money to finance the cost of learning (if there is an associated cost where you live), finance your own car and the associated insurance and maintenance expenses and responsibilities. If you cannot find and maintain a job that provides you with the finances to support a car and it’s attendant expenses and responsibilities you are not mature enough for car ownership.
Want it that bad? Quit blaming your parents, quit getting in trouble (and blaming them for it), grow up and get to work earning what you want.
