Two Funny things on the Prius... I was recently passed by one in my STI doing 90 mph... wonder how much fuel savings there is at that speed
The other, my in-laws bought one, and quickly brought it back. The thing would shift into electric mode and it was very unnerving; the car would seem to "stall". They had issues all the time with the changeover, the car died and would not revert between modes. It stranded them three times, and then they returned it and bought a camry
