Not to be flip, but everything. Obviously every car is different so if you push it as hard as you're personally capable, you learn how it responds dynamically to the laws of physics and to your inputs. For the 5V BW relative to other cars I've driven hard at speed, I learned that it is generally surprisingly benign. On the street its massive amount of hp and torque do not make it feel "normal" or benign, but on the track it felt pretty much like a regular 3-pedal car, except that you could mostly drive the entire short and tight Spring Mountain course in 3rd (you can grab 4th briefly at the end of the front straight). I had to more consciously squeeze the throttle rather than simply matting it in a ham-fisted manner like I can do in cars with < 300 hp, but the "squeeze" could be made quite quickly with a little practice. Of all the control inputs, I also learned that I like the brake-by-wire least. On the track they provided perfectly adequate stopping power, but they felt rather "wooden" to me, a bit devoid of feedback and more tricky to modulate than the steering, shifter, or accelerator.
