Well, I think my question is rather simple (but the answer might not be):
Is there any advantage in buying a hybrid (say a Prius) if you're facing a long highway commute?
My commute is 144 miles per day, four times a week, seven months a year.
I read that hybrids "promise" 45 mpg on highways...but is that true even if the commute is very very long (battery charge goes down to nothing and you're left with the engine).
I would really like to hear the opinion of some knowledgeable people.
Thanks a bunch
