For some bizarre reason, the towns through which I commute every day (I drive the back-roads, not the freeways) like to tear up their roads every six months or so - I'm not kidding it seems like they finally get them repaved and a week later they are all ripped up again.
Lots of the time, they'll do one lane at a time. So when the traffic is low, like after rush hour, people will drive partly or even completely in the other lane - to avoid the unpaved lane that they 'belong' in.
Whenever I see an SUV do that in front of me, I make a point of sticking in unpaved lane and keeping up. Even unpaved, the roads are easily within the capabilities of any half-decent SUV. The speed limit is usually 30 or 35 so it isn't that fast, just that whenever I see an SUV avoiding even the most minimal off-road experience it makes me think *pu*ssy* and I have to show them how lame they are. They probably just think I'm a dumbass for taking the bumpy road.
Bet you purposly drive thru puddles to roostertail tailgaters too
