Many city folks just don't get out when a snow or ice storm comes around. So a 2wd with a LSD factory option works for them.
I'm on the other side...... where getting around a muddy worksite or hauling out of a wet pasture make a 4wd necessary.
I also living in a rural area 5-7 miles from the highway and drive on county roads getting to those highways. Most snow/ice storms the county may be several days before they show up to plow the roads.
My 2500 Dodge/Cummins 2wd sits in the tractor shed when the roads have any ice or snow on them or if a pasture or worksite is too muddy. This is where my 3500 DRW 4wd or the wifes 1500 chevy 4wd shines.
There is no one size fits all as we all have different needs and driving scenarios.
