Yea, see this is my concern. I don't plan on regularly pushing the car to its absolute limits, but I do regularly drive faster than everyone else on the road and I want a car that can do that safely. The Tesla I'm sure is capable of doing that, especially with the safety features disabled that might try to kill me during spirited highway weaving. I felt the body roll in the MYLR and it was wayyy more than the M3LR, but the M3 also has more roll than my WRX. Now it's tough to tell how much of this was impacted by the tires on the test drive vehicle, but there's definite body roll regardless.
The acceleration and skid pad is not, as someone else mentioned, the only one most important factor in a car's ability to handle. The body roll and stiffness of the suspension is much more important to my needs because I consistently am passing other cars and sometimes needing to navigate with a more responsive touch to maintain a safe rate of travel at my preferred velocity.
It is also of extreme importance to me that I can enjoy the car the way I want to enjoy it (obviously), and that the car can do what I want it to. Now whether this is obtainable through new coilovers or something else, I'm interested in improving the handling at least to the degree of my WRX. I can safely drive that to its limits, and that's what I want to understand the most out of the MYP. This will come with time, but if I can make the limits bigger, I'll be capable of being a better driver.
