What is the correct procedure when an examiner asks you to parallel park, but the only available space is directly blocking a private driveway or fire hydrant?

1. Identify that parking there is illegal under the Highway Code, inform the examiner politely, and continue forward to locate the nearest legal parking space
2. Park across the driveway anyway because the examiner commanded it
3. Switch off the engine in the middle of the road and walk away
4. Park on top of the sidewalk to leave the driveway open
