A Prius owner reflects:
Driving home from NY after Thanksgiving, pointed out to my wife the pickup who was no more than 20' behind the trailer that was passing me.
My solution when I see that in my rearview: Slow down. They might like the mileage gain, but people have no patience for driving slow. They'll get off your bumper.
Oh yeah, BTW: I averaged 53 mpg over 700 mi round trip for Thanksgiving. But then, you'll find me tying up traffic driving the speed limit in the Granny Lane!!! Don't hate me because I'm saving gas...
