Finland’s Sensible 4 passed testing in extreme weather conditions. Freezing rain can affect the hardware, and their recent test in June 2022 proved that the cars, and self-driving software, and underlying hardware were not affected by the freezing conditions or the rain. Sensible 4 can also remember which part of the street to park on alternate-side parking days, and it knows how to adjust to snow and snow plowing tracks on the road.
Sensible 4 will have a great future in Finland, where it snows almost every day in winter.
