If you want to practice without breaking parts you can practice in a wide open area. You can use cheap corner dots to mark off an imaginary track. Or if you don't have the money for some corner dots, use old soda cans or 2 liter bottles. Fill them lightly with rocks or sand. That way, the wind wont blow them over, but your car wont take damage from hitting them.
