Depending on how the car works and if the brake lights are engaged when regen braking it could be considered a hard braking event and increase the likelihood of the car behind rear ending you so it’s not clear the insurance company is wrong in this. But as noted it does depend on factors they likely don’t account for.
I would really like a constant power mode where I could set a cruise control like setting where the maximum power was limited to allow me to go downhill without regeneration but to limit the uphill power usage to something reasonable.
