Got a source for this claim?
I bought a new ICE vehicle six months ago, in round figures it cost me $13,800 (that's the on the road price of the base model, including a couple of minor extras and all applicable taxes).
The electric version of that exact same vehicle has a list price of $31,300. No, that isn't a typo. The salesman seemed faintly embarrassed when we enquired about the EV version.
The depreciation curve for ICE vehicles is fairly well understood. So is maintenance and the reliability of key components (we've had a previous ICE from this manufacturer that ran for over 9 years without any out of the ordinary components failing).
Before we purchased, a salesmen noted that EV technology is changing so rapidly that even if you do feel like handing over $30k for an EV, in 5 years time it may not be worth very much. Whether its batteries will take you very far is also less than clear.
I wish all of these things weren't so, I'd happily own an EV, but not at current prices.
