See what happens is that when we get snow here they plow the hiway , but the cross sections ( where you would have to cross northbound lanes to get into the southbound lanes ) there is snow piled up so deep there you usually can coast your way into it , but trying to start out and get out of it on the road is where the problem comes in . You need to be locked !! Then the Atrac does its thing ( which is awesome ) and your off.
When I have been driving on snow/ice covered roads ( hiway or rural or country) and not having to cross the median strip , just crusing along the VSC can save your butt and keep you straight. You almost have to let go of everything and let it do its thing. I don't like that ! but it is what it is.
As far the the 4R 4x4 system , I think its awesome with the ATRAC , but not being able to turn off the VSC is a drawback. Being able to disable the ATRAC to would be a bonus too , but the throttle can over ride the brakes control anyway.
Like I said the only reason I was looking at a used Tahoe/Yukon is for the room for my dad. Also a BIG factor is that they hold crap for resale and can get a used one a few years old for half the price with only 30-40K on it .....pretty sad , but true.
I really have not been impressed by anything I saw or drove so far, compared to the 4R . I'm just looking around at options , probably end up keeping the 4R which is not a bad thing at all.
Just got to figure out how to get dad to fit in the 4R better.....lol. I'm so glad I did not inherit that 6'11" frame and weight. He's never been fat , always pretty muscular and used to weigh in at 365lbs/6'11''. Big , big guy. Great father too. It's pretty sad that at my age (45) my 70y/o dad could put me through the wall......lol.
And if I just kept the 4R then I'll have to put my 1" leveling kit on before winter.
