You gotta be kidding... around here the Priusesesessss (Priuii?) are rolling chicanes, especially on the 80-mph speed limit toll roads. Granted, I think the 80 limit is too high for many vehicles like my Cherokee and generally use the right lane at about 75, but even then I have to jump left to dodge the Priuses all the time.
And there's no need... I KNOW that they can cruise over 80 if the driver wants too. Maybe they just don't feel safe at that speed, I've always found them a bit underwhelming as far as chassis and suspension goes. Great tech, not so great car fundamentals IMO.
German car drivers are the ones that seem to think they've imported part of the Autobahn along with the car... :-/
And then there are the ricers. Phart-cans, "ground effects," and giant wings are dwindling in numbers (through natural selection, I presume) but there are still a bunch out there... driving too fast and leaving a trail of blue oil smoke. :-/
