There are so many variables that have to be considered that even their report (and I haven't read their whole report) likely doesn't cover true costs, and there are other factors besides financial - time costs, environmental costs, etc.
Answers to these types of things are rarely as simple as they seem. Electric vehicles have no emissions, but the electricity that was created to charge them does (except in the miniscule nuclear/wind/solar areas in the US). There's also a huge energy loss through heat transmission as electricity is transmitted through power lines. A lot of the "costs" also depend on whether or not the industry eats those costs or outsources them to someone else. For example, roads are built/maintained at least partially through gasoline taxes; electric vehicles don't use gasoline so they don't pay those costs of usage.
I don't want this to sound like I'm against electric vehicles, because I'm not - I think for sure they make sense versus continued consumption of a non-renewable resource like petroleum, and eventually they will likely supplant most use of ICEs (but not entirely). I just think people shouldn't think too much of themselves because they drive an electric car; truth be known, the lowest cost thing you can do is not drive at all. Next up after that is driving a fuel efficient vehicle that's already on the planet versus one waiting to be built (i.e. a used car).
