Agree…in addition, consider that added weight in the trunk of a FWD has a negative effect when going up hill in slippery conditions. This happens when the the center of gravity shifts rearward, making it more difficult to retain traction. When FWD looses traction, you also loose steerage. In a RWD the rearward shift aids traction with minimal effect on steering.
Bottom line…in slippery conditions, keep unnecessary weight OUT of the trunk in FWD, esp. in hilly terrain. Also…a FWD has better traction going up hill in reverse. Keep that in mind when parking in a sloped driveway in slippery conditions.
After all…any vehicle that depends upon ultimate traction (tractors, race cars, police cruisers, other emergency vehicles etc.) have a vast majority of RWD or 4wd. For a good reason.
