ReGen level shifter pedals for Model 3

[Topher]

Would setting the regen to low via the main screen not work?

No. 1) It only has one level of regen. I am hoping for infinite levels. 2) It would require moving eyes off the road, instead of just twiddling a thumb wheel.

Can someone explain to me what the advantage is to have a knob/handle adjust the strength of regen power when you can adjust the regen power already precisely and conveniently with the pedal where my foot already is?

Same reason that we have cruise control. 1) It eases the work that the foot must do 2) It allows a set and forget process.

Thank you kindly.
