I wasn't trying to paint you as an EV basher. But regen was not the issue in the reddit post. Traction control governs accelerating and braking in all road conditions - but again it can't create traction. Someone could read your post #383 and (falsely) conclude regen caused the spin/accident...so I looked further.
Whoever said Teslas cannot be configured for regen is mostly wrong. On all Model 3 and Y: Hold is the "one pedal driving" setting, max regen. IIRC Roll is no regen, or close to it and Creep is the middle ground - I may have that backwards.
On the (much lower volume) Model S and X, evidently Standard and Low are the only Stopping Modes now. I don't know if Standard mode regen enables one pedal driving on Model S or X...or it's a lesser mode than MY Hold. Audrey will know.
I have never driven the OG Roadster, so my knowledge only goes back to 2012 with Model S.
With the Model S in 2012, Tesla started with only one driving mode (later named "Roll") and two regenerative modes ("Standard" and "Low").
I feel "Roll" mode is simply the best and most natural driving mode for an EV and it matches very well with a perfectly-shifted-always-in-correct-gear manual transmission vehicle. When stationary, the vehicle will feel like it's in neutral and will roll freely if on an incline. When you depress the accelerator, the motor will apply torque and you will accelerate. At speed, when you lift-off the accelerator, the motor will apply reverse-torque (regen) proportional to how much you lift. This feels like closed-throttle engine-breaking with perfectly-rev-matched downshifts as the vehicle's speed reduce. The amount of regen possible is proportional to motor speed, so as it approaches zero RPM, the regen fades to zero, which brings you back to "neutral" as you come to a stop. This driving mode is a really idyllic experience for someone coming from a manual-transmission performance ICE car.
But, many people are so used to the unfortunate side-effect of the fluid-coupling torque converters in the stupid slush-boxes (automatic transmission) coupled with an ICE that can't stay still and must run at "idle" RPMs that they think/feel that "idle creep" is an actual feature! Unfortunately, in 2012, Tesla gave in and introduced (
software_update_1.13.16_0.pdf) "Creep":
“By default, Model S does not slowly move forward when you release the brake pedal like cars equipped with automatic transmissions.”
“With an electric motor there’s no need for this, but some early customers miss it. Using software updates, we can upgrade every Model S with a ‘creep’ option which customers can enable using the 17 inch touchscreen.”
Driving Mode = "Creep" coupled with Regen = "Low" really emulated a slushbox.
Up to this point, motor torque (acceleration & regen) was only ever controlled with accelerator pedal while the brake pedal only controlled the friction (hydraulic) brakes. And up to this point, the only way to hold the vehicle stationary was to hold the brake pedal (or use the "hill hold" feature, which required depressing the brake pedal to initiate it)
Then, in ~2019, they Tesla introduced the term "stopping mode" and gave you three options: "Creep" "Roll" and "Stop". The new "Stop" mode is basically one-pedal driving like many other EVs. The car will blend in friction brakes as regen tapers off, bringing the vehicle to a stop (and holding it). This is the first time friction brakes can be "controlled" by the accelerator position.
In 2020, Tesla removed the "Low" regen mode.
In 2021, the refreshed Model S and Model X were introduced with no driving mode options and no regen options. It is permanently locked into "Stop" mode and "Standard" regen (One-pedal driving mode).
My 2018 Model 3 still has three driving modes and regen settings, but I think my dad's new Model Y doesn't (I didn't take notice of this).
