Turn the wheels and leave in gear even if the handbrake failed the car wouldn't move very far.
Relax and be confident when reversing back up a hill i told my dad to leave his new tiguan on the road untill he got used to the handbrake i got a phone call on the very day he took it home he had ignored me and the car was mm from the garage door
I calmly got in the car and reversed the car off the drive for him.
