| Dwight Silverman, Houston Chronicle. Relevant to GSS Energy Use chapter 9. Excerpt: ...I don't drive it too aggressively, but I do enjoy its ability to get moving quickly. ...I used to get irked with Toyota Prius owners... notorious for driving below posted speed limits, slowing to a stop far out from a stop sign or light, taking their sweet time when the light turns green or creeping through parking lots so silently that they startle pedestrians. Sure, with my Mustang averaging about 15 MPG in city driving, I envied Prius owners' claims of 50 MPG and better, but really... do they have to be so pokey while doing it?

The Prius can achieve decent mileage at 55 mph, but as it goes faster, mileage drops precipitously. That's why Prius owners tend to be the ones in the right lane, letting everyone else pass them while speeding.  ...Of course, the way you drive in a Prius is actually the way you're supposed to drive, according to every defensive driving class I've been forced to attend….
