Yes, but aren't you losing traction when the tire is mostly off the ground, too? Same thing, really. The power isn't lost if it's not getting put to the ground anyway. It's obvious to me that these cars possess FAR too much rear bite, and a wonky design and setup just follow too much tire or rear weight. At least with a diff and the proper rear geometry for a race car, the rear tire might not be putting power down, but it would be still stuck to the pavement and distributing weight and traction.
I'm not saying a differential is a better mousetrap or anything of the sort, but it most certainly appears as though there is a LOT of room for technology and forward thinking to improve these cars, for sure.
