im in Michigan and we get plenty of snow here. I'm imagining the difficulty driving through fresh snow in the center of the road. I am imagining a removable spring loaded plow to scoop away snow before driving hough it.
The regenerative braking controls seem like they could be way more seamless and intuitive. Rather than dialing up or down the regeneration with a knob, why not integrate a linear potentiometer into the brake pedal stroke. The first half of the "brake" could be ramping up the regen, and the second half could be engaging the standard friction brakes.
