I have figured out a way to make long train journeys (which constitutes all journeys - even to the next stop) more enjoyable. The carriages should be split up according to conversation type: dull and uninteresting, business and executive, spies, opionated, arguments. We can then get rid of First Class etc and just have these categories.
It could mean more revenue for the train companies (who I think are really organised crime) who would have more gradings of ticket type and they could fine people heavily for starting up the wrong type of conversation in a carriage. They could also fine people if they don't start a conversation suited for that carriage during the journey.
The approach could be extended to all modes of transport: buses, planes, boats, national health, etc.
