Why is off-tracking a bigger factor for a double or triple combination than for a single trailer?

Pick an answer

1. Off-tracking is identical regardless of the number of trailers
2. Additional trailers eliminate off-tracking entirely thanks to their own fully independent steering axles
3. Off-tracking decreases as more trailers are added to a combination
4. Additional trailers add more length and hinge points, which can increase how much the rearmost unit cuts the corner
