afx114, I can’t speak for flu, but modernizing the fleet is NOT the same as replacing the fleet with hybrid vehicles. The cost different between hybrid vehicles vs comparable I4 models are huge and would take at least 5 years with $4/gal gas to break even when driven at an average of 15k miles a years. If the miles are mostly highway, then it would take much much longer to recoup the difference since the highway mileage is negligible between I4 models and hybrid models. Also, we haven’t even consider the extra cost of maintenance and how long those batteries last before it need to be replaced.
