As a driver in places where it snows... I'm curious about how it will handle:

1. Fresh unplowed snow where there are no lane markers visible.

2. Significant banks that take up half a lane with two lanes in each direction.

3. Ice (often one doesn't start going through an intersection on a green until you're 100% sure that every car has cleared - I've been on both sides of this, where you don't go because there's a car sliding through, and the car sliding through because slick ice doesn't care about brakes)

4. Hard braking (the "drive slow and use the brakes lightly for a long while")

5. Cold car things. Electric battery life in the cold (heater for the passengers). Wipers frozen to the windshield. Accumulation of snow on the window. Excess snow on top of the car (considered an insecure load).

Tangent for the "how do you handle lanes when you can't see any" ... old school approach: https://ieeexplore.ieee.org/document/833362

> Driving a snowplow during whiteout condition is one such example. In order to improve the safety and efficiency of the snow removal operation, a supplemental steering guidance display was proposed and instrumented in a Caltrans snowplow. The guidance information was calculated based on the magnetic markers embedded under the roadway. Operations were successfully conducted on a 6.25 km freeway over Donner Summit on Interstate 80 in California during the 1998-1999 winter season.
