Why can motorcycles be overseen despite having their dipped headlights switched on?

You answered correctly. Motorcycles are easier to overlook even with their headlights on because they are much narrower than cars, making them less visible in traffic, especially from the front or in mirrors. When motorcycles accelerate quickly, they can cover distances rapidly, so other drivers might underestimate how soon they will arrive. Additionally, if riders wear dark or inconspicuous clothing, they can blend into the background, further reducing their visibility. Always remember to watch carefully for motorcycles, check your blind spots, and anticipate that their size, speed, and appearance might make them easy to miss on the road.
