A good bus driver always shows other road users?

Answer: A — Courtesy

A good bus driver always shows courtesy to other road users. Courtesy in this context means treating others with politeness, respect, and consideration. Showing respect and kindness to other drivers, pedestrians, and cyclists is key to promoting safe driving practices and avoiding potential accidents. Therefore, options B, C and D are incorrect. Indifference, which means a lack of interest or concern, would lead to an inconsiderate attitude towards others on the road and could potentially cause harm. Assertiveness and dominance can be perceived as aggressive and controlling, which is not conducive to promoting road safety. Thus, option A, courtesy, is the most appropriate behavior for a good bus driver.
