If it's a choice between franchising for the cities and nobody caring what happens anywhere else because the money is always better spent by local authorities elsewhere (and they certainly can't afford to buy/set up their own bus companies), which feels like the current bus policy, then full nationalisation starts to look really attractive.....
* One wage/conditions structure
* One fare/ticketing system
* One app/tracker/feed, with a helpline for the elderly/disabled
* One marketing/livery strategy
* Clear financial position (operating budget and long term investment)
* Clear customer charter
* Buses properly represented in all major planning/strategy decisions at the DfT or in local authority processes
* Standardised vehicles
* Efficient depot network
* Massive purchasing power (fuel, tyres, parts, ancillaries)
* Adoption of best practice (operations, policy, training)
* Certainty for the UK bus manufacturing sector
Even in an ideal world where combined authorities and councils/unitary authorities are directly running all buses, you still end up with all downsides of a patchwork provision, even a postcode lottery. Some of the local authority boundaries in use now are truly bizarre, but because it costs too much to figure out who would be due what slice of the pie, they still form the basis of the ticketing strategy.
People generally don't live/work/travel according to administrative lines on a map, barring of course, the coastline of Great Britain. So why not make that the extent of the nationalised bus operator's domain? The idea that buses are local so they should be run locally, is a red herring.
Stagecoach is a perfect model - head office focused on group level matters, with local managers given very broad leeway to make local level decisions. It produced a uniform service from the Highlands to Kent via Manchester and wherever Red & White is.
Londoners/Mancunians need to get out more if they think TfL is the nuts in terms of buses. Imagine what Stagecoach could do with TfL/GM level funding but a free reign to design services so they best met a specified minimum national contract. A nationalised operator would of course have a matrix organisational structure, with horizontal reporting into local authorities and passenger groups, as well as vertically to HQ.
And without the need to present a corporate image to the stock market, it's a fair bet a nationalised GB wide entity would incorporate local identities into its national branding/livery strategy. And without the need to trumpet the fact buses are integrated with other modes in certain places but not others, we could be rid of things like that horrible yellow mess in Manchester, and return to something a little less....stupid. Maybe even get rid of boring London red.
The old NBC went for plain red or green because they weren't actually a national operator. They needed to make sure people knew which bus was run by them, the professionals, and which was run by some bloke in a council department, a PTE or the GLC, who may or may not also be looking after trams or bin lorries. True national scope removes that need.
One Chief Executive Officer responsible for the village bus service in Crimply Bottom and Misty Corner, the turn up and go services in Big Smoke, the Moors buses in...all the Moors, the inter-urban and commuter services in MetroTown, the post tram network in County Town and Tiny City and of course, Bussy McBusFace in Resort Corner. A bus is a bus. It's not a tram or a train. So why let people who care more about trams/trains run them?
It will probably never happen, chiefly because Mayors like playing with their toys too much. It's certainly not cost. You can probably buy every bus operator in GB outside of London/Manchester for pennies in the grand scheme of things. And it's not like that would come under day to day government spending, it would be in the investment column, paid off over decades, with the efficiency savings kicking in hard within just a few years. One uniform supplier, for example.
