Not in my experience. Two main offenders: mini-vans and Buicks. If you get behind a Buick, you might as well walk. And vans are generally driven by emasculated men or soccer mommies.
Not in New England. The subbie has replaced the *I-know-better=-than-you* Volvo drivers of the past. Just look at their bumper stickers...*Co-Exist* *Obama-Biden* *Greenpeace* *My children is an honor student ...* *I brake for...* ....yada.
Must be different in your neck of the woods. :)
Be safe out there!
