You need to think of regen braking as being more like downshifting a traditional vehicle vs applying the brakes. And downshifting is one of the better ways to control speed on slippery roads. Regen is essentially resistance in the motor, just like downshifting. To avoid too much regen causing the wheels to lock and slide, you’ll learn to feather your foot off of the accelerator to slow down vs completely taking your foot off like you would with traditional braking system. Although different, its prettty intuitive, so within a week it will all seem very natural. Biggest challenge is if you have multiple vehicles, one with regen and one without, and go back and forth between them.
