Yes, you are right about the price of gas going back up again. It already has started moving in that direction. Back in 2005 when Katrina hit the gulf coast, gas hit $3/gal for the first time. That would have been the right time to think about hybrid and electric technology.
That was over 3 years ago. Toyota has been building hybrids since the 2000 model year and selling them in the US, i believe. They now offer 3 of them. How many does Chrysler/Dodge offer?
