If you are asking about the method of turning your front wheels into the curb when parking on a hill, it can help reduce the risk of brake failure.
Don't leave the engine on. Set the parking brake and turn the wheels toward the curb.
Turn your wheels heal toward the curb, set the parking brake. This way, if the brake fails and transmission slips it will not roll into traffic.

That is potential energy.
When parking uphill with a curb, turn your wheels away from the curb and set the parking brake. When parking uphill without a curb, turn your wheels towards the edge of the road or shoulder and use the parking brake. When parking downhill with a curb, turn your wheels towards the curb and use the parking brake. When parking downhill without a curb, turn your wheels towards the edge of the road or shoulder and use the parking brake.
It is harder to ride a tricycle than a bicycle up a hill since a tricycle uses recumbent form of cycling. This will make it difficult to go up hill than a bicycle.

You want to park the car with the front wheels turned toward the curb so if the emergency brake were to fail the car would simply roll into the curb and stop. Put the car in first gear if it is a manual tranny and set emergency brake.
they do that so it does not roll down hill
