BE - questions could be:
1) Do you own a landcruiser?
2) Do you drive at 10kmph in the middle lane?
3) Do you indicate left when you mean to turn right and vice versa?
4) Are you quick to temper - e.g. if a car in front of you fails to set off within 0.5 seconds of the lights going green you honk your horn?
5) Your horn is more important feature on your car than the brakes?
6) You come off the roundabout from the innermost lane?

Answer any of these yes and you fail mental driving test.
