My opinion is that it's acceleration capabilities outperform it's handling. In a straight line, there is not much that can keep up with you. However, it's a rare occasion when you even need to push it that hard. In fact, just moderate application of the accelerator will leave the vast majority of cars and motorcycles way behind you. You'll only really use launch mode or max perform the car if you're really trying to make a statement to someone else. The car is extremely stable in a straight line launch, especially with traction control on. The AWD is amazing.
However, a note of caution, don't confuse the straight line acceleration performance same for handling in turns or uneven roads. In my experience and in my opinion, the car gets light and loose at higher speeds. If you hit a bump at high speeds you may feel the car rise up and that's not a comfortable feeling. I recommend caution anytime you may find yourself at speeds higher than the speed limit. My caution also applies to curvy roads. The Tesla is not a PORSHE. You are not going to handle corners like a small high performance car. While you might be able to keep up or likely beat a high end porshe on a straight line, if the road turns, you'd better be breaking first or you might find yourself off the road. This is my opinion. I'm not a professional driver, but I don't like the feel of the steering wheel when going around curves at high speed. I love driving up in the mountains, but the steering wheel, even in sport, has too much play for me. I'd prefer something stiffer to allow better precision driving while corning at higher speeds. I've never lost traction, the 21" wheels are incredible, but I find myself oversteering the entry and understeering the exit...again, the pros may attribute this to my abilities, but I've yet to get a real good feel for the steering wheel.
Depending on where you live, everyone will want to race you. Hopefully you can encourage them to accept your invitation to meet you at a legal and safe location where you can exhibit how much superior your car is than theirs...cause it is....
