The problem with EV's for many is still price. I just bought a 2 year old certified preowned truck and to get a comparable Ford Lighting it would cost me $75k (XLT with extended range battery, no pro model). The Lighting would cost more then double the price of the used truck I bought and have a 320 mile range versus the 500 miles I can get out of a tank of gas. I have family up to 6 hours / 400 miles away that I can drive to in my truck without refueling.
For a lot of potential EV buyers, including myself, people will jump into the EV market when they can buy a 2-3 year old certified preowned at a good discount versus buying new. How far is that away though? When could I buy 2-3 year old Ford Lighting XLT with an extended range pack for say $45k used versus $75k new? For that to happen a lot of EV vehicles need to be produced and purchased. It's going to take years, maybe 10 or more in my opinion for those scenarios to happen.
On another note gas at my local Costco just dropped to $3.90, with their credit card at a 4% discount (cash back) that's $3.75 a gallon.
