When parking facing uphill on a street with a raised kerb, in which direction should the front wheels be turned?

1. Turned to the right (towards the kerb), pointing directly into the sidewalk
2. Turned to the left (away from the kerb), so the back of the front tyre rolls into the kerb if the vehicle rolls back
3. Kept dead straight with the handbrake released
4. Turned rapidly back and forth until the steering lock clicks
