Improve traction control and regen to better handle icy road conditions where max regen may cause the back-end to slide out.
From what I’ve heard, regen on icy roads can cause the car to become unstable and let the back end break out (like when using the handbrake on a regular old car). People are advised to only use “low” regen to avoid this. I thought this was very strange: why can’t traction control limit regen when the back starts to break out? Did Tesla just buy a standard ESP package for normal cars that does not know how to handle regen? So my feature suggestion is reprogramming the traction control so that it can handle problems with regen. Electronic stability should work in any circumstances, including when using regen. If the car can release the brakes and even brake individual wheels, shutting off regen to stabilize the car should be easy.
Moderator: We don’t know if this is a real problem or not, having never experienced the issue, and it sounds like the submitter hasn’t either. On total ice, it’s not clear that any system short of chains will help.
