Dumb question: how can I reduce throttle pedal sensitivity?

Good reading here:

FWIW, my W210 E55 has a much more sensitive throttle tip-in compared to my W211 E55. In the W210 it is very easy to chirp the tires on initial throttle application whereas with the W211 I have to consciously "stab" the throttle. Takes a few minutes to adjust to the quirks of each car when I switch between them.
With the Miata, no issue about chirping the tires.... ;-)

i think a driver's ability to handle an aggressively programmed drive-by-wire system depends upon his prior experience with performance oriented cars or motorcycles. The more he has driven "performance" cars or bikes in the past, the easier it becomes to more comfortably meter the throttle.
Motorcycles especially are great "training grounds" for throttle control, as their power to weight ratio is much better than that of cars, and ANY large displacement motorcycle, whether a cruiser or a crotch rocket, requires a well calibrated throttle hand to prevent quick disaster!
Notaballer is a relatively young guy, especially within this forum. He also has only had the C63 a couple of months. Also, some people have great physical sensitivity while others do not. Don't discourage him. Just encourage him to "get more practice" by driving the C63 more.
I always remember the story about Bill Cosby and the car that Carroll Shelby built for him. This was decades ago (1960s I think) when a "fast car", even a Shelby, had maybe 300rwhp at most (They claimed a lot more but used "Gross" hp versus net hp), but the throttle linkages were deliberately aggressive on the faster cars to make them seem even faster. The first time Cosby drove his Shelby, the throttle sensitivity scared him so much he ultimately asked Shelby to buy the car back. No kidding. Cosby even did a comedy monologue on it, which was funny as Hell - I recall hearing it when I was still in high school.
So please, ease up on Notaballer.

Best thing to practice is using your toes and not your foot. Place your foot touching the gas pedal. Curl your toes down like you are making a fist with your foot. Don't move at the ankle, just the toes. That is all you need to get going from a stop in a smooth manner. Once you've mastered that, you can work on giving it more until you get comfortable with the torque.

Only when your eyeballs literally pop out of their sockets or your retinas detach under braking. Before that point, you can't have enough brakes.

Back on topic . . . tweaking the relationship between pedal position and throttle body opening is pretty common on drive-by-wire cars. I recall reading that EC does this with most of their tunes. See also Sprint Booster, PedalMax, PedalRemap, etc. They just fool your butt-dyno into thinking you have more power. I don't like it. In addition to the jerky/jumpy first-gear starts when cold, a non-linear pedal makes accurate throttle modulation a bit harder in fast corners on the track.
