Driving and parking in the wrong lane.

I don't know what it is about this part of the United States (or whether this is something prevalent) but I find it odd that people park their cars on the wrong side of the road, pointed in the opposite direction of traffic.

In order to do that, one has to cross the street into oncoming traffic and pull up their car so that the headlights are facing .... yes ... oncoming traffic.

Why?

Maybe it's a Pacific Northwest thing?
