I think one of the other challenge is for high density housing and on-street parking.
Also, plant and machinery - a 20T excavator can't run on batteries if you want to maintain productivity. You'd need 4+ of them to do 1 job that a diesel powered excavator could do (since they'd need to be charged and thus losing productivity). As such you need 4x more batteries and more steel to create the same productivity for construction. I'm using construction as an example since they use thousands of trucks, and plant daily - they are almost more significant than commuters.
If sustainability is the main aim, car pooling, and reducing single occupancy cars is far more effective - as well as mass transit systems.
Also the recycling of electric cars becomes problematic - I wonder if a 10 year old eV would still run as well as a 150,000 mile diesel car? We don't have that data at the moment.
Don't get me wrong, I'm not anti electric as I say, I do think it is a mild distraction (but a positive one) of the bigger picture. None of these changes will happen over night - 30 years from now I'd be surprised if even a 1/10th of the vehicles are all electric. That said, I'd be delighted to be wrong.
