You've hit the nail right on the head Neptune. The problem isn't what sort of means we have to travel, it's the ridiculous amount of travelling itself.
Any overhead view of out cities worldwide is the same, huge numbers of cars travelling in opposite directions 24 hours a day on almost as much road space as there is living space. As if that's not too much already, it's multiplied by buses, trams, trains planes and boats. It's not only hugely costly financially, it blights the environment, wastes space and time and is potentially damaging to health and human relationships.
We live in area A, work in area B, shop in area C and have leisure activities in area D. Saying that most of us spend 20% or more of our waking lives in various forms of travelling might seem unlikely, but we do actually waste our lives in that way. We really need to take a long hard look at this system and devise better completely new ways to construct our living environments. The total of the achievable benefits is potentially immense.
