First show a proper cart of how the batteries charge capacity decreases with time.
Miles driven is a much better metric as charge/discharge cycles ages a battery more than age.
Such a chart was done on the Tesla forum where owners reported miles and the max range after a charge. The chart showed a very small deterioration with well over 90% capacity remaining after 100K miles (the highest mileage reported).
Second what proportion of the cars cost is the batteried which will have to be replaces in N years time
We haven't found the limit for Tesla batteries yet. How will we know what a replacement battery will cost in X years where X could be upwards of 15-20 years?
What is the 'carbon' footprint of the vehicles manufacture and how does that compare to the typical combustion engine cars manufacture and lifetime use.
All aluminum (easily recyclable) car with very few moving parts and no tail pipe emissions vs just about anything else... I'd think it compares very favorably.
