Explanation:

The question asks about road-sharing challenges with buses. Comfortable seats (irrelevant to road safety) and engine loudness (not a key challenge compared to other options) are incorrect. Frequent stops blocking visibility and unpredictable routes directly affect safe road interaction, making them the main challenges.

Answer:

Their frequent stops can block your view and their routes can be unpredictable.
