I am concerned about the fact that the strength of regenerative braking cannot be adjusted, since Tesla remove the option to turn regen off. I wonder what experiences people have had with the Tesla on snow and icy roads when slowing down and braking. When regenerative braking kicks in is it more likely to skid than an ICE car would? I am used to taking the foot off the accelerator to slow down gradually in such conditions. Does Tesla automatically reduce the strength of regenerative braking when the tires slip?Are there any tips for driving on show and ice?
