The ability to, while you are driving, never get pulled over, never get a speeding ticket & never get a parking ticket. Even if someone calls you plate in, the police will say they will note it down, but the magic stops it from entering, and the police forget.
You never hit traffic. Every time you start driving, every car, except for police, magically disappears from the road. Police will follow their normal route like nothing is odd. They will not target you. Whenever you get to your destination, all cars magically reappear on the road again
You never hit a red light. Even if 20 cars are ahead of you, the light turns green when you get close and doesn't turn red again until you are past the light
You never have to pay for gas. You have a magical credit card that allows you to never be depleted as long as you are holding it. It can not be lost or stolen. You cannot pay for other people's gas, and you cannot fill any cans up and sell those. You may only use it to refill the car you are driving.
For clarification, all of these only apply if YOU are driving. If you carpool, take an Uber, or are a passenger, it does not transfer over to the driver. You may drive any car you want, however. None of these is tied to a car.
