In a state/area that NEVER sees snow or ice, maybe; since it doesn't make sense to drag around all that extra weight for a 4wd system you'll never use. Then again, just get a wagon/minivan, as they do everything better than an SUV, except for the snow/ice/offroad/4x4 stuff. However, in areas where snow/ice do happen, you shouldn't even be able to order them (SUV's) new as 2wd.
I can see the use of a 2wd pickup/van, for hauling,etc.. (especially things like mason dumps,etc..), but an SUV has no business being 2wd. They are an abomination.
As for the guy w/the Kia, that was a funny come-back. However, be thankful he at least has the good sense/courtesy to not be on the road when it gets bad. I HATE getting stuck behind 2wd cars/trucks in bad weather, when I'm driving a 4x4, and could be easily and safely going MUCH faster. (ie, 30mph, instead of ohhh, say 10mph). On top of there ill-equipped vehicles, so many people have no clue how to drive in good weather, let alone snow. They ought to know better and just stay home.
