Mostly, hype about eco-friendly e-cars is just hypocrisy and wrong way to promote it.

It goes down to battery: increase capacity at least 3 times per kilo/pound of it's weight and increase service life of it from modern day 6-7 years to 15-18. After that e-cars will sell themselves, tho i don't envy regions where materials for batteries are mined as it's way more messier than oil (if it's not tar sands- that's a disaster) and humanity will have another energy crisis on it's hands, this time from electricity shortage due to skyrocketed demand.
