Of course I am, it goes to the heart of just about any discussion of public transport in this country.
Quite apart from "omnibus" being an archaic word you take its derivation far too literally. The idea that buses could be all things to all men might have had some relevance in the days before widespread private car ownership; in this day and age they have to justify themselves rather more clearly. And as long as Deregulation remains in place that is bound to result in them being concentrated on where they are most heavily used. And yes, that's politics for you! If you want to see real changes you need to persuade rather a lot of people to change their voting habits.
What is "Remote Rail"? I take it that it's a comment on the fact that there isn't a railway station within easy walking distance of every sizeable community. Yet in this country aside from London and Glasgow the suburban network around Manchester is the best there is in terms of geographical penetration, though Liverpool doesn't do too badly either. But because it isn't convenient to you it doesn't deserve funding?
Radamfi has already provided the correction to the erroneous assumption behind this question.
How can you possibly assert that all floating voters "have cars and are paid well"? Are they deemed deserving of your criticism just because their votes don't produce the results you want? This is a democracy after all. So many of your comments are dripping with the politics of envy so beloved of the hard left. Perhaps you would prefer life under a hard left government. Do China or North Korea look like good places to live? Or could it be more simply you rather regret your decision not to become a car owner? Decisions have consequences...
There is little difference between all the main parties when it comes to public transport. Its just a tiny minority across all parties that "champion" he bus aka the bus passenger. This is partly illustrated by your own comment about people changing their voting practice. Trouble is that buses are not the top of the political agenda for the vast majority, but I suggest are second or third to a significant proportion of the public. De-regulation per se is simple. It doesn't matter if your a motorist or not, or whether you have differing views on Brexit, Immigration, general public spending, the deterioration of the NHS and the Police, you will find virtually NOBODY commenting on social media in/around Greater Manchester who agrees with Bus Deregulation.
Yes, the concept of OMNIbus is being diluted but to answer your question based on local stats rather than national ones; counting each station as two (platforms operating in opposite directions, there are about 130 Heavy Rail stops in GM; 185 Light Rail and 12600 bus stops. The national figure is relevant to "Remote Rail" though I concede they are about a decade out of date and I don't know if they include Light Rail, and especially LUL. That figure was based on average walk from home to public transport stop served at least 60 times a week - and it was 400 metres for Bus and 2.7km for Rail. 2.7 km (1.6 miles) is a considerable distance for all but he fittest in society, especially if undertaken twice every working day, and would take something like 30 minutes to walk.
The thing about "deserving funding" is three fold.
The amounts invested in Rail (especially in the South East) is mind boggling to Taxpayers worried about their bus service being withdrawn; their schools being closed; their waits in A&E (often with genuine life threatening circumstances or just severe pain) growing from 4 hours to 5 hours to 6 hours etc.
We have a stupid attitude in this country (and not just public transport) that Capital spending is always good, and Current spending is always bad. If there is tens of billions of pounds a year floating around for investment, why are existing trains failing due to staff shortages?
Finally, even with the relatively better off benefitting, spending all these billions on Rail (heavy and light) it would be more palatable if it took millions of cars off the road. But at best, the current policy just removes congestion from city centres and places it around local stations. At worst, it isn't the car that is seen as the enemy, it is the bus. Hence off-peak fares heavy rail fares undercutting bus fares and fares on such as Metrolink undercutting buses when the journey doesn't involve entering the regional centre.
