No, it doesn't drift, this car plows.
I sure wish it drifted, not that I drive it hard that much anyway. Yet I have to dispute the conclusion on the video.....the car in the video drifted for a few moments then went right back into its massive understeer mode. I presume that they had TC off, and even with the wet track, its tough to get this car to hang its rear out and sit. In fact, although I've only driven the car hard a couple of times, I have yet to gain a solid feeling of where my traction limit is, and to keep the car from wanting to plow. How much of this is the lack of toe and camber,suspension tuning, etc. and the tires is still an open question until we get to see how a Tesla Sport handles.
My guess is that a Tesla Sport has a shot at actually drifting.
btw, is anyone here actively organizing a Track Day for Teslas? If so, I'm interested.
