Llandaff North to town by car takes around 10 mins, a few more mins at busy times.

On the bus it takes 30 mins and you get to listen to people inexplicably talking much too loudly, swearing a lot and infuriatingly playing shite music much too loudly on their phones.

Plus, it'll be far too hot in the summer, far too cold in the winter, the seat may have chewing gum stuck to it and if you have the gumption to be over 6 feet tall then you're going to break your kneecaps on the seat in front any time the bus stops.

EDIT: Oh, and the bus stops tend to have the glass smashed so the wind howls through while you wait for a bus that sometimes simply does not arrive.

Why they keep replacing the windows with glass is a mystery to me, they must be made of money. When I lived in St. Mellons they put plastic ones in that evidently are a lot less fun to smash every day.
