When planning a lesson route for a learner who has only recently started driving, what should an ADI prioritise?

1. Choosing the busiest, most complex roads to maximise learning speed
2. Using the same fixed route for every learner regardless of experience
3. Letting the learner choose any route without regard to their current skill level
4. Selecting routes that match the learner's current stage of ability, avoiding unnecessary high-demand situations too early
