I think it's funny that Toyota is so proud of itself for its recent creation of a hybrid vehicle that gets 52mpg. It uses a small gas engine, an electric motor, and a plethora of sensors and high tech components to achieve this efficiency. Not bad gas mileage really but I don't find it very impressive since in the late 1980's Honda was getting 55mpg from their carburated CRX HF. They can be impressed with themselves when they get something a bit more astounding like 80mpg.
