Seems fairly logical that a sustainable vehicle will be simple in nature.
That rules out anything later than Euro 3 and also any EV. Less is more is a relevant phrase.
Agreed.
Currently, EVs are overly complicated for no obvious reason (other than due to marketing and profit). Very few manufacturers build low-cost EVs. The big flat screens and plethora of driver aid systems and all the other bells and whistles all contribute to the high RRP and the low reliability.
A car that is driven by an electric motor is essentially cheaper to make and is inherently more reliable than one driven by an internal combustion engine and auomatic transmission and all those complex emission reduction systems.
At current there are only two things that drive EVs prices up and are unavoidable: recouping the investment in R&D (which will go away in time), and the cost of the battery (which should get resolved as new technologies emerge).
But apart for these, the high cost of modern EVs is the result of fluff that makes EVs unnecessary complicated and potentially unreliable.
Some manufacturers compensate for this by providing very long warranties, e.g. 5 or 8 years, but this only pushes the problem further down the line.
The Chinese manage to make an electric truck that costs from $2,000 USD, and although not street-legal in Western countries, it does demonstrate that there's a market for simple no-frills EVs that are cheap to make, cheap to run, and are more reliable that the complicated and expensive current creation from main car manufacturers.
