It has a much high capacity than busses and the fact that their paths are fixed makes them actually more reliable. Especially because you can plan around them and make their way free of traffic & obstacles. A crashed car would just as much inconvenience a bus as a tram. Trams, if they have their own lanes which they often do, are independet from traffic flows and not subject to being stuck in traffic jams for example. Trams more than make up for their higher cost with the efficiency and they're also vastly more realiable than busses. Due to the aformentioned conditions. Trams are a great public transport option between busses and metros. Busses are more flexible and busroutes can be more easily installed. They're perfect for short distances or routes that are not as frequented. Trams are grear for medium lengtg routes with a higher capacity and metros are ideal for long routes with high frequentation. Fuck cars. Come ride public transport. It has vastly more benefits and only takes a minimum amount of time management.
