Why is following distance especially important for a passenger vehicle carrying a full load of riders?

Pick an answer

1. Following distance is unrelated to passenger load
2. It only matters for vehicles longer than 40 feet
3. A fully loaded passenger vehicle always stops faster than an empty one, since the added weight is assumed to improve tire grip on the road
4. A fully loaded vehicle needs more stopping distance, and hard braking risks injuring unrestrained passengers
