any day in the winter over understeer FWD.

As the guy in the vid says, tires make the biggest difference, most RWD cars are on low profile performance tires which are just skiis in the snow. Put on some all-season (or better yet winter tires) and the advantage of RWD and balanced/slight oversteer come into play.

The whole "FWD is way better in the snow" mantra stems from marketing by the big 3 (Ford, GM, Dodge) when they went all-in on FWD drivetrains for ease of packaging on the assembly line and their horrible weight distribution and poor handling was written off by the marketing team as "better in the snow". Simply because understeer (or no steer) makes it less easy to flip 360s if you give too much skinny pedal, and to inexperienced drivers this makes them feel more "safe" behind the wheel.

But really, you are trading in "over control" for "lack of control".

FWD just sucks. Sucks for handling, sucks for driving feel, sucks for maintenance and DIY.
