I think a big reason why some public transport isn't liked much is because there aren't enough seats and it isn't always clean. Getting a seat when it's really busy is very hard, and this makes the trip exhausting and uncomfortable. Also, dirty conditions on buses or trains, such as trash and dirty seats, make people not want to use them and choose other ways to travel.
一部の公共交通機関があまり好まれない大きな理由は、座席が足りないことといつも清潔でないことだと思います。混んでいる時に席を取るのはとても難しく、それが旅を疲れさせ不快にします。また、ゴミや汚れた座席などの汚れた状態は、人々がそれらを利用したいと思わせず、他の移動手段を選択させます。
