At Nottingham, buses move cyclically while here, the few buses I've used seem to be moving linearly.

That's an interesting observation. However, just a little clarity? Linearly in what way?

I am now living in Devizes, Wiltshire, and I have observed how different the bus system is here compared to places like Leicester. There is Stage Coach here while Arriva and First Bus are in Leicester. Stage Coach is far cheaper, and the fair system is structured differently. If I take the bus from Devizes to Swindon, a 40-minute ride, cost £2. If that was Leicester I would probably pay £4.
Also, the buses in Leicester come every 10 minutes, while here in Devizes it's like on the hour.

Overall, I agree with you about how different all the cities in the UK are. Living on my narrowboat and visiting cities for intended periods made me realise that:)
