Ehhhh.
As it stands, there is no logical, engineering, or economic basis for your conclusion.
Sure there is. I used to lease a Civic Hybrid, which I was able to squeeze 50 MPG with a range of 600 miles on one tank, over the course of three years, with minimal pollution emissions. That could not have been achieved with either gas-only or electric-only, considering the pollution costs of getting that sort of mileage with either of the methods solo. How much pollution was created to get me 600 miles of range with electric-only? How much pollution was created to get me 600 miles of range with gas-only? How much pollution was created to get me 600 miles of range with the hybrid?
I am going to bet the hybrid, but there is also another trade-off we have to consider...
I acquiesce to the fact that there is a fuckton of pollution generated by manufacturing all those batteries to put in the car in the first place.
So maybe everyone is correct. Electric only for the win. I dunno', I'm not an engineer. But then again, how many others here are? My intuition says hybrid is the least-impactful to the environment.
