Edit: I really didn't expect such a response to my comment or I would have elaborated. Primary factor is cost, cost of replaceing the battery and initial cost of the vehicle purchase.
I do not have money to buy a new vehicle and there is no way I'm going to buy a used electric vehicle. A used electric vehicle will probably Also need a need battery. Until longevity can be proven I'm going to take that gamble.
Also repairability is another very big factor in not getting an electric vehicle for me. I am going to be buying a used car I don't think I will ever buy a new car even if I had the money and a used electric vehicle is not in the cards until they can prove longevity and you can't do that with a lithium ion battery.
In addition the electronic parts including the battery use rare, precious metals that are becoming increasingly rare. We don't even have a way to recycle those batteries as far as I am aware. I'm not saying we don't need a better alternative, but, I don't think that's it.
