I guess the main interest in this thread was meant to focus around the impact of snow on regeneration elements.
When you lift off the power the car starts to increase the resistance in order to harvest energy. This probably interacts with the braking management and stability control software. This causes pressure on the tyre/road footprint in the same (opposite) way that acceleration does.
In the event the snow is under tyre the resistance will be different and I wonder if that reduces the regeneration or confuses the ESC tools?
