Learn to love the drive by wire throttle. Here's the thing: it's very on purpose non linear throttle. If you very slowly depress the throttle you get very fine grain throttle response, it's so you can climb up a bump without a jump in speed once you get on top.

Try this: bump into a curb perpendicular then slowly add throttle just 1% at a time, you can climb up on the curb where once on top you won't accelerate once up on top.

The throttle curve is designed to help at slow speed and works too greatly improve traction and it works STUNNINGLY.

I've driven out of 3" of ice that I parked in as water without any wheel spin! That would not have happened with a linear throttle!

I've upgraded my tires to run on flat with an extra 500# capacity I can carry 1500# load no problem. 6600# gross on occasion though the rated Max is about 6000#.

The other day I drove one wheel onto a pair of wheel chocks to raise up the car. As always just climbed right up.

One time I accidentally drove over when I backed up I forgot I chocked the tire while working on the front wheel. I barely felt it it just went right over (4" tall wheel chock).

When you accelerate from a stop on low friction surface no matter why, you get more acceleration every time because of it.

Now on to the ABS: find a big open parking lot that is very low friction and start into a strong curve and hit the DISC button. When you hit the traction limit the car will yaw so fast you may end up sideways or backwards!

The car absolutely requires ABS for stability. When my abs has failed the car feels worse than my rear drive Camaro Z28 In the snow.

You have control over ABS not kicking in just don't push the pedal so hard:

If you are skidding you are not stopping as fast as if the wheels are still turning so do some test firm brake applications to determine how much force you can use without abs kicking in and use slightly less. Skidding will add 10% to stopping distance but you may end up backwards.

Full ABS stop on low friction will add 30-40% to stopping distance but you can steer into the obstacle of your choice (car, tree, fence, house). No car was this more dramatic on than my Z28!

You can let up pressure a tiny bit if abs kicks in and get 33% better stopping power if you get abs to stop cycling. You'll never get better stopping by manual brake application. Maximum stopping is achieved when wheels are right at the limit of adhesion with no skidding or ABS. The best way to achieve this: ABS on (in case) but brake at the limit of grip without ABS kicking in. If abs kicks on let up 5-10% on brake pedal and instantly get more grip
