It's fair, considering buses take a long time anyway. a) There is a limit to how fast they can go, lower than that of cars b) They take a long time anyway, considering the amount of stops they stop at. For example from where I live to Canterbury in the car takes half an hour, but on the bus it takes a full hour.
I couldn't leave the "likes" with a tally of 666. I'll be on the 667!
