fair enough and not trying to start an argument just looking at all practical aspects. I agree with the concept but what about cars that are stuck and need a tug but do not have a "good" point to pull from, how do you think they are pulled out? Are you implying that if and when they are pulled out they are damaged ?
This guy was looking ahead of a potential stuck...measure of a guy who has "been there and done that" and for that reason, I point out the relatively simple fix.
Not everyone will do this, nor should they because they probably will never need it...heck, they are leaving spar tires off of brand new cars and trucks these daz but that doesn't mean you will never have a flat.
As for yanking cars out of the muck and snowpack....yes you sure can screw up a car more so than a truck and if you have never seen a car dog trackin down the road, you missed the likely reason it is doing it. Happens all the time to these light steel framed cars and trucks. Yank it a bit too much and damage can be done alright.
The point is that there is no really good place to "hook" stuff to pull it out... of course how stuck you are and where it is "hooked" to get unstuck are important things to anyone who understands that these modern cars and trucks just are not made for yankin out of the ruff!
