For what it's worth, I only used like five buses in total but I noticed that the trips/commutes felt like we were going straight from one end to another. At Nottingham, the buses sort of meander about different settlements and two of the same buses always meet along the route but on opposite sides of the road, making it seem like they're moving in a cycle.
Something I also forgot to add is that in Leeds, bus drivers give you change after you pay. In Nottingham, you are required to pay the exact price for the bus ticket.
