Yeah, and all those people who can't afford to buy new cars or who don't have access to alternate transportation will just have to suck it up and choose between gas and food or rent/mortgage payments.
A smaller wagon would save her money on repair costs, even if her gas bill was the same.
Yet, you fail to adress whether or not it would meet her needs and standards. Clue: There's a lot of factors involved in choosing a vehicle. I'm getting close to dropping my minivan for a truck that gets half the gas mileage but which, as the minivan has problems with, does the jobs I need done.
I was replying to your comment about people who can't afford new cars. I'm saying those people eventually do get new or used cars, despite the fact they shouldn't be able to afford it, and then make the poor choice of getting the larger car. If they 'need' it for status or to sit high and make them feel good, then I think thats a want, not a need. So these people should not get to pollute the planet for free. If people have a genuine need for a truck, thats slightly different, but I still don't see why we can't put a battery in that too. If the big advantage of hybrids are regenerative braking, then a larger vehicle would produce more regenerative braking, and the advantage is still there. Even if a bigger battery is more expensive, the biggest profit margins are in trucks anyway, so the car companies excuses are just that. And if every car/truck in America is a hybrid, then you will see the price of those batteries go down.
You also fail to address that the true cost of polluting will be charged to us all in the future. The current cost is already high and barely being charged in car/fuel prices. I agree that people should be allowed to buy what they want, but not to a point where it hurts the rest of us.
