I have completely lost interest in this conversation. go build your dream ev power city man, your passion outshines mine.

So your question is could an efficient transportation system be designed around individual pods transporting through a dedicated network? I don't know, it doesn't sound like the most efficient to me.

Well it is two different things - public transport such as trams and buses is different than privately owned vehicles. We need to be pushing people away from private ownership and investing into better public transportation. How exactly this is done I would leave to people like you.

​

I'm not going to be able to give you any specific figures, too much context is needed - there are so many factors to be considered. The need and desire for people to be able to travel freely has to be balanced with the impact that the transportation method has - in terms of space required, energy needed, environmental impacts, infrastructure requirements etc.

There are plenty of parts in the world in which small vehicles can be justified - an Australian sheep farmer can make good use of a land rover for example. But for most modern city based lives any sort of private transportation quickly becomes prohibitive.

It is a large problem that would take a lot of joint up thinking to solve, involving city design, how and were we work etc.

I know a lot of people feel passionately attached to their vehicles and it represents independence and freedom for many people, but it is just not viable on a large scale.

Individual transportation.

​

Put it this way - if you were designing the transportation network for a planet of 8 billion from scratch, would you choose to assign each individual a 1.5M * 4M 2 tonne vehicle which will need to be stored when not in use nearby to the individual where ever they travel, which travels at a dangerous speed in close proximity to peoples homes by low skilled and often tired and distracted operators?

Cars evolved from a different time with different needs in a different world. It just does not make sense for the world we live in today.

what is EVs?

I think we aim to do the best we can do. There is no end goal, just do our best.

efficiency is using the least amount of energy to achieve the desired result. There is no hard value, but it is obviously not the most efficient means we have available to us for transportation.

It is no solution anyway. Private transportation does not scale no matter how many tunnels and overpasses and super mega motor highways we build. It is simply not efficient or practical for individuals to be transporting themselves around in 2 tonnes of metal.
