they had such a product years ago, a spray can of alcohol, grit, and who knows what else. I remember using it when I was stuck, usually on ice. It helped a little, IIRC, in some situations. Don't remember who made it, several different brands.
the test itself is invalid.
By the looks of it, the first car had Pirelli winter tires
the second car had Bridgestone? winter tires.
All season tires also were completely different between cars. Theoretically this could be the reason for the outcome shown in the video. I do not doubt the recommendation however.

The point is the difference between an all-season tires and a winter tire(I think Nokians by tread design). I happen to have two vehicles that weigh pretty close Subaru WRX(all-seasons) & Subaru Legacy(winter tires) and find the same thing is true on lateral traction and braking.
