What do you expect? The author wrote the study for Exxon Mobil. As others pointed out, you have to divide by about 5 to 7 to account for the losses in going from gas to available power at the wheels. Even then, gas wins against batteries by about a factor of two. And batteries are only getting better very slowly. On the other hand, the cost per mile for an electric car is less than half the cost per mile for a gas powered vehicle. And the car is actually simpler. The economics will favor electric cars soon because of this. The car won't be able to go 300 miles in one trip though. But If we have charging infrastructure in enough places, almost all trips can be satisfied with 100 mile range or less. For a big road trip, you'll just rent a gas car, similar to how today you rent a U-Haul truck for that odd occasion where you have to move a huge pile of stuff.
