There should be some sort of "crack down on lookie loos". Can't remember how many times going into Richmond on the 91, where I have had to slam on my brakes coming over an overpass because everyone on the other side has slowed down to 50 to look at the cranberry farms or the low flying helicopter/spray plane in the fields next to the road.
Or when you are on the opposite side of the road (barrier and all) of an accident, and for some reason, YOUR lane is going slower than everyone traveling in the opposite direction.
This emoticon captures my feelings perfectly actually:
Some sort of privacy curtain does sound like an interesting idea - though I wonder about the potential for harm to the responders because drivers aren't able to see the individuals and thus may not be as cautious or able to respond accordingly if someone steps onto the roadway.
