After considering the posts regarding highways, railways, byways, airways, terminals, networks, subsidies, costs, profits, cross subsidies, taxes, excises, various exemptions, demographics, bail ins, bail outs, the taxpayer, tax evaders, fare evaders, socio economics boundaries, regional vs metropolitan areas, redistribution of population, places of work, access to services, climate change, energy, environment, politics, corporate structure/governance, infrastructure, multiple authorities, state and federal regulations ... to name a few and also thinking about sea lanes, rivers, harbours, ports, economic zones, engineering, technology, freedom of navigation. I think the solution is to nationalise all domestic transport services into one National Public Transport System (There2There). Free for everyone. Overhaul the whole system and place it under one administration. In ten years you could produce the cheapest, most efficient, most effective, environmentally friendly, public transport system on the planet.
