I know of very few people who drive a car that gets 40mpg. My Honda CRX used to get more than that 25 years ago. I don’t think that we made much progress in fuel efficiency.[/quote]
How many exurb do you know? Comparing a CRX to modern cars is quite ridiculous. Do you know why your CRX got such good gas mileage? I bet you a CRX w/ modern day engine making 70-90HP and weight ~1800lb can get even better gas mileage than the old CRX.
Care to tell me what a 4000+lb 420 HP vehicle 25 years ago that can get in highway mileage? Currently, you can expect around 25MPG highway.
