What is the proper hand positioning on the steering wheel during standard driving on open roads?

1. Both hands on the wheel in the '9 and 3' or '10 and 2' clock positions, with thumbs resting along the wheel rim rather than hooked inside
2. One hand resting on the gear lever and the other at the bottom '6 o'clock' position
3. Both hands holding the top '12 o'clock' position with wrists crossed
4. Driving with only one finger on the steering wheel spoke
